Project 2: Light Box Self Portrait






For Project 2, I decided to do a self portrait.  I created a half tone pattern of my face using a plugin for Adobe Illustrator called Scriptographer.  I created two vector portraits, each a inverse of the other.  Now that I had vectors, I was able to lazercut the image on to two 11×11 panels.  I printed the image on transparency and put the lazer cut vectors on each side.  By ordering the layers in different ways, I could create different effects.  I could create a 3d holographic effect by placing the transparency in front and putting the panels behind.  This blured the holes and blended the two images together.

Project 1 – Light and Shadow Panels






Project 1 recap:

I came into this project interested in two main ideas which were primarily generated by the fact that I am hoping to in some way link these discoveries/interests to my studio project of designing a tall building (500′). Though somewhat distinct I was hoping to integrate them into a single system. The first idea was that I could design a form which would diffuse and, if necessary, shade daylight. The second idea was that this form should be interesting and dynamic enough that when strategically lit it could become a powerful form/pattern making device. The idea was that this single surface or structure could provide adequate glare free daylighting during the day and at night become an iconic beautifully revealed form.

My first panel, shown as the second set of images here, was based on the geometry of a lobsters eye. The curved form and square opening work together to diffuse and concentrate natural light. Theoretically I found this to be a interesting investigation. The ideas of bio-mimicry interest me quite a bit. However, in practice to be effect I think this approach requires a very scientific, research based process which is difficult to develop in a short time frame. In fact I think the reflectance value of the material I was using was significantly off and the proportions of curvature and depth were probably ineffective as well. I think the simple interlocking eggcrate method of constructing the structure could possibly we continued. The second panel was simply a test in manipulated LEDs, which I think would be a great system for night lighting since it is very controllable and directional. Here I was trying to create a parallel circuit of 12 LEDs so that I had the practical knowledge to implement this lighting system into future projects. I learned a fair amount, though the lighting effects were not particularly interesting unless the photos were taken into order to capture motion and then I found you could in effect paint with the light. For the third panel I wanted to be a little looser and experimental. The first two had a very top down approach so for the third panel I simply played with a variety of simple cutting operations.

For the final project (and for next week):

I think my initial goal to create a dynamic surface which integrates natural day lighting and artificial night lighting is still valid. The first project helped me identify two possible methods of construction which I am interested in and can push forward – eggcrate, and single flexible surface. I think for this next project and into the final I am going to push both of them forward, though in a much more integrated way. The eggcrate will shape the form and the flexible surface will provide the skin. If I can get a handle on it, some selective LED lighting will help reveal the structure. The main obstacle for me is finding an appropriate way to integrate this with studio, and it is difficult because the studio design process is just getting started and is much more complicated.

Light and Shadow: Thoughts on Final Project

For the final project, I want to experiment with self shading panels and ideas of daylighting optimization.  I was thinking of combining this project with ideas from my biomimicry class.  I want to look at how different plants and flowers funnel light.  It would be interesting to see how lighting conditions change as the angle and intensity of the light change.

There is still a lot to think about with this idea and it may not be fully formalized in the short amount of time given.  I am in the process of learning rhino.  I think the CNC router will be useful in creating the final project.

A Proposal

As a culmination to my studies in this class, I am interested in modulating the effects of light to define space. How can something with solid form be used to create a projected mediating atmosphere through visual phenomena?

This installation will be site-specific, creating a mediating zone between private studio space (my desk) and public kitchen space.  I want to study how shadow and color reflection can redefine how a barrier is perceived.  As the site has south facing glazing on either side of the dividing line, the “sundial” projection is maximally mutable throughout the day.

With Lisa Iwamoto’s Digital Fabrications as inspiration, I am interested in exploring the 3D mutations of 2D surfaces.  I will use Illustrator and Rhino to create a digital version of the project for testing and laser cut the pieces for assembly from thick cardstock or crescent board.

Light and Shadow: Final Panels







These are the additional panels created to explore light and shadow.  After my first panel, where I created a pattern printed on acetate, I tried to experiment with other materials.  My second panel consisted of different sized circles.  Every circle also had a different length.  I combined the circles together in a random pattern.  It was interesting to see how the length of the shadows changed as the angle of the light changed.  Some of the circles appeared thicker under different angles.  The most interesting aspect of the panels, though unintentional, was how the circles cast shadows on themselves.  It added a new layer of detail and complexity and created an interesting result.

In my third panel, I tried to experiment with curved glass.  To do this, I hollowed out a incandescent lightbulb, and removed the filter so that nothing was left except the glass.  I placed a cardboard circle (left over from the second panel) around the end to cover up the sharp end.  I then used a needle and thread  and the cardboard ring to sew the bulb to the panel.  When placed infront of the projector, the bulb acted as a prism and split the light into green and purple.  The most interesting effects happened when I filled the bulb with water and then removed the water.  This left the bulb with droplets on the inside.  These also reflected the light and created an amazing visual effect.

Light and Shadow Assignment 1

This was a study in creating compositions of shadow through small 12″x12″ panels.  The intention was to test what is possible in mediating direct light into shadow, examining a variety of options.  It should be noted that I did not completely understand the final project assignment until talking with students this week. Knowing the scope of the final project helps me understand the structure in which exploring these options will help the development of the final.

I began the study with a simple examination of hardline form used to create shadows on a surface a few inches from it, with enough diffusion to partially disguise the original form.  I scavenger hunted a little bit, finding a chair back and water droplets creating interesting shadows by themselves.  I also tested layering,with strips of masking tape, found objects like templates projected onto other forms, and paper folding.  I used a variety of materials: plastic bags, styrofoam, paper, crescent board, mirrored surface, wire mesh, tape and toothpicks.

After noticing the effects of changing shadows, I became more interested in creating thick panels with structure hidden behind screen.  As light moved behind these panels, the appearance and location of the structure changed, creating uncertainty of form.  I suspect I was strongly influenced by Junichiro Tanizaki’s In Praise of Shadows, which describes the way in which darkness and ambiguity can improve the quality of space, objects, and events, giving dimension and a more spiritual perception to daily life.

“The beauty of a Japanese room depends on a variation of shadows heavy shadows against light shadows – it has nothing else.”

Speaking about the atmosphere of a painting under the eave of a dark Kyoto temple: “The lack of clarity, far from disturbing us, seems rather to suit the painting directly.  For the painting here is nothing more than another delicate surface upon which the faint, frail light can play.”

There was also an instance in which I used the reflectivity of the plastic bag to mimic a watery surface, which perhaps was inspired by this quote: “And surely you have seen, in the darkness of the innermost rooms of these huge buildings, to which sunlight never penetrates, how the gold leaf of a sliding door or screen will pick up a distant glimmer from the garden, then suddenly send forth an ethereal glow, a faint golden light cast into the enveloping darkness…”

I also was interested in how shadows could disguise complete structural form and mislead: in this example, the structure is the wire mesh, but the vertical shadows appear structural.

In the end, this exercise was really enjoyable and got me thinking about the importance of shadows, but I am not sure that I will be able to carry any of these ideas further into my digital fabrication proposal.  In the next step, adding color, I am approaching the exercise with more focus towards the final project.

Light and Shadow First Experiments





Here are a few of the results of my initial light/shadow experiments.

I was mostly interested in the light/shadow effects involving some bright green moss I found. I used led’s for the lighting which is very directional. The moss tended to disperse the light, though the light levels where really low and it was difficult to get good photos with my camera. In the room it was more like a moss disco ballroom. I liked how the light tended to reveal the structure of the moss in a dramatic way.

I also played with using water, bubble wrap, and shape tracing patterns. One of the images I took over break of the coast at night, and the way the light bounced off particles in the air was unusual.

More to come…

Light and Shadow: Shadow Panels












On the first day of class, during our 30 minute experimental shadow excursion,  I thought it would be cool to experiment with the translucent nature of trace paper.  I drew a pattern on a piece of paper that attempted to express a concept I have struggled with in the past:  Harnessing randomness and uncertainty.  I blew up the drawing in the copier, scanned it and printed two different versions on trace paper.  By overlaying the images with a slight gap, it created a interesting effect.  Unfortunately, It would not cast a shadow.

The logical next step was to print the same patterns on a translucent material.  This time, using a projector as the light source, I was able to cast a shadow.  I experimented with different surfaces…smooth wall, crumpled trace paper, my face.  All produced interesting effects.  One unintended consequence was the interesting reflections generated of the reflections.  By rotating the “light manipulator,” I could produce green, purple and white reflections.

The next step will be to experiment with cutting and folding paper.  I don’t think the pattern I chose was very successful for this project because the shadows produced are hard to differentiate.  I may choose another design for some of the other panels.
