How we built the Infinity Portal

Some of you may have seen our most recent monster creation at Alchemy or Atlanta Mini Maker Faire - The Infinity Portal.

The Infinity Portal is a 10 foot tall archway with a 7 x 4 ft infinity mirror inside of it. The mirror is made with two-way acrylic, so you can push on it to warp the effect for people on either side of it. It is lit with addressable LEDs, so there is a counter-rotating rainbow vortex in there too. You may remember seeing our write-up about prototyping the design a few months ago.

Defying all expectations, the thing actually survived both events that we brought it to! So we're really happy with it and will find a place to keep it in the mean time.

We actually (surprisingly) did a pretty good job of documenting this build, so we cut it together into a video to show how we built this huge, epic piece of art. Enjoy!
