Off the Ground by Jochem Faudet. This series of angular tabletops sports folded sheet metal legs that grip any or corners. The legs can be ordered separately to hold any surface that is 20 to 25 mm thick.
I had a similar idea around concrete table top and copper legs. Made of oak and bent steel tubing, Clip is a simple, portable and foldable table. Inspired by a paper clip, the base and top come apart and the top can be used separately as a tray.
