After experimenting with the first draft, I found the cardstock to let too much light through. The effect of a lamp within a lamp was completely lost. I decided to experiment with another lamp that would be made out of a thicker material and have less perforations. The main concept was to project the pattern from this lamp onto the larger one.
Upon inserting this lamp into the bigger one as well, I discovered the patterned effect to be too minimal. However, it WAS interesting to use a colored bulb with this pattern.
