This is the prototype for my entry to BBC America's Doctor Who contest. It's made out of clear acrylic cut with a laser cutter lit with a blue LED.
This is what it looks like lit up
The clear one is the one one I went with but I tried a few other ideas.
I used the cardboard to test out the measurements I had made before cutting it out of acrylic.
From right to left: Blue acrylic, cardboard, white acrylic, and clear acrylic
Here's some pictures of the building process.
This is the electrical box with the top off, also cut from clear acrylic. It's powered by a 9V battery.
