Yeah, I've been bootstrapping a DIY version of the Kaon shelf. I bought their nuts and bolts kit (you can now also buy the bracket itself, which would make it much easier), and have been playing around with it for a couple months.
Most recent thought was that I'd have the shelf in rails and have the option to slide it out to use as a table at camp. Haven't started construction of the new rails yet, but did find some left over C channel from long ago to try out.
I tried some 3/8" plywood - was too flexible. I'm now using a wire grid intended for advertising / retail displays.
