Working With PVC

So our latest project in studio, our last one actually! Required us to use two previous materials from other studio projects and then to incorporate one new material along with the other two. We had to make an object that created a field of light using only one compact fluorescent bulb, the bulb I went with was a 100 watt bulb and my three materials were cardboard, paper, and 1" PVC couplings. I honestly still am not quite sure where I was drawing inspiration from, but rather than inspiration I was trying to develop a concept from everything I was looking at. And everything I found myself studying I was never getting close to thinking of some concept. The only thing I've found that I really seem to like is that the moon takes nearly 30 days to complete its lunar cycle. Here is the documentation of what I've got!
