The 8 ft tall signs are made with diffuse LED rope light in a CNC'd lightbox.
Our camp serves hot steamed Chinese pork buns (Bao) from 12-1 AM. That's when the HOT sign is used in sequences, and a servo changes the first W into an N so phrases like "Hot Bao Now" can be shown.
Made with Illustrator, Inventor, Shopbot, Adrunio. Sign font is a modified Monoton.
