PSI setup

I have been toying with some materials to use for my PSI lenses. The main concern has been that they need to hold up against poking fingers. The next thing is the space needed to diffuse the hotspots, and since I am using a multicolored LED to create any color I want it also needs to help mix the colors. After many trials and errors I think I may have found a cheap solution.

If you have or know someone who has cats, the litter can come in huge white plastic buckets. These buckets need to be able to hold 20lb-40lb, so the plastic is nice and string. I cut one of the buckets up and did a few tests and they work great with one layer of material and even better with 2 sandwiched together. The setup consists of 1 or 2 layers of litter bin material and a LED source. The barrel to contain the light source is the smaller cup of a bar tenders jigger with the bottom cut out of it. Since the jigger is metal, it reflects the light just fine.
