Aaron Springer brings us these twisty fabricy stage design.
They used a spandex/cotton blend fabric they bought from A.C. Moore and hung it from the ceiling. They folded it in half then rubberbanded that side to a point. Then they zip tied it to their ceiling tiles.
They pinned the other corners to the floor and hid their small LEDs behind the fabric. There was also a small black light next to each LED to sort of bring out the color of the fabric.
