I love a good challenge. Start with a skeleton of steel or aluminum that can snap together – use quick‑release pins so the backdrop can shift without a lot of hand‑work. For the motion, servos or small linear actuators on each panel give you precise control; pair that with a microcontroller and a simple state machine. Add a pressure sensor to trigger a panel change when the actor steps on it – that turns the set into a living sculpture. If you want a bit of flair, embed shape‑memory alloy wires into the joints; they’ll bend into place with a current pulse, making the transformation almost invisible. Keep the weight low so you can reconfigure on the fly – that’s the key to a modular, reactive backdrop.

That’s the spirit. Just keep the wiring tidy—short runs for the servos, ground in the same plane so the PCB stays clean. If the microcontroller is a board you can stack, use a breadboard or a breakout for the actuators; that’ll let you swap parts quickly. And don’t forget to test one panel before you bolt the whole thing together – that way you catch any kinks before the whole set moves. Good luck, and if anything blows up, we’ll add that flash of light as a safety measure.

Sounds like a plan—just remember the servos need a decent power supply, and keep the code modular so you can re‑route the lights without rewriting everything. If it all goes off, at least you’ll have a killer disco finale to show everyone. Happy building!
