Here's our show setup. Photos are from C2E2 this year.
We worked with an industrial design agency to design and build these. Overkill? Probably, but the goal was to have a super high quality, modular system that we can arrange in various configurations, display slabs, be easy to setup and tear down, and easy to travel with. There are four racks total, two on each side that lock together. One rack can be built in about 5 minutes. Strong enough to be climbed like a ladder. Made from powder-coated aluminum. Two racks can be shipped in a single case which weighs around 100lbs, pictured below.
It was not cheap and we are not producing them for sale or selling the design, but I'd be glad to share additional photos if you want to use it for inspiration.
