Fund Lavinia's Puzzle Art for Burning Man

Hello! My name is Lavinia and I am a Sacramento based artist looking to build my first art piece for Burning Man. I plan to build a 3'x3'x3' mounted and fully functioning Rubik's Cube-like puzzle that will be called "Eustress'd?". Puzzles have been a form of calming me during anxiety-ridden moments. I thought it would be a great gift for the people on the playa to be able to stop and have a little bit of fun stress while solving something familiar placed in a bizarre setting. The supplies I'm looking at to build the piece is costly. Any help is greatly appreciated!
