Schrödinger's Cat Cube. I used Printrbot's Blue Moon Glow-in-the-Dark PLA. I put a little design on the lid which is not visible when glowing. The glow is nice though over all. The reason I decided to do a Schrödinger's Cat Cube with this filament is because I printed the cat inside the cube hollow and intended to use a white LED to light the cube from the bottom activating the cat and allowing it to glow through the semi-transparent walls which ended up not working like I had envisioned.
