Large Scale Tunnel
Click the image for video!
I made this large-scale pop-up light tunnel scene by scaling up one of the scenes from my Tunnel Book and cutting it out on foam core on our laser cutter. The lights are interactive, they can be controlled using a panel of 12 potentiometers.
The tunnel is collapsible for storage, and when displayed pops-up to 3ft wide x 1.5 ft high x 4 ft deep (about 6in deep when collapsed).
