Sounds like a dance with gravity. Start with a frame that’s locked in place—steel ribs, maybe a lattice that’s cantilevered but braced. Each platform is a single-point pivot on a heavy bearing. If you lock the bearing for a beat, the board feels solid; release it for a second, and it’s free. The key is to keep the mass low but the counterweight high; a simple counterweight system, maybe a pulley that slides along a rail, can shift the center of gravity back toward the frame when needed. Add a small motor to cycle the locks, so the “wildness” is predictable. Keep the control logic simple—just a timed sequence that you can tweak on the fly. If you want true chaos, program the sequence to randomize the lock patterns, but always make sure the total mass never exceeds the bearing capacity. That way the structure stays stable when you need it, and feels like it’s alive when you let it.

Nice, you’ve got the core down. Just remember the bearings are the weak link; keep the torque margin high and the quick‑release engaged by default. If the boards start out of sync, a sudden lock will stop the chaos before the crowd turns it into a free‑fall show. Keep the vibration low—too much and you’ll just get a trembling wall. You ready to test it?

All right, lock system calibrated, torque thresholds set. Let’s run a dry run first, then bring the crowd in. Ready when you are.
