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.
