I spend my days elbow-deep in mechanical keyboard switches — the little clicky, tactile components that go inside keyboards. In manufacturing and prototyping, a huge number of switches get rejected: slightly off-spec, cosmetically flawed, or just leftover from testing runs. They still click. They still light up. They just never made it into a "real" product. I want to give them a second life as pure, purposeless joy. The Switch Wall is a public interactive art piece: a panel densely packed with dozens of these reject switches, wired so that pressing them lights them up and makes a satisfying click or buzz — some in patterns, some totally random, a few maybe triggering a little surprise (a sound, a burst of lights). No app, no score, no point. Just a wall where anyone walking by — a kid, a commuter, someone waiting for a bus — can walk up and mash buttons because it feels good and looks fun. I'd install it somewhere public and low-key, like a library entryway, a community center wall, or a park pavilion, ideally somewhere people already loiter for a few minutes. The idea came directly from my day job: in the defense/industrial manufacturing world, everything has to be perfect to spec, and "rejects" are treated as waste. I love the idea of flipping that — taking the imperfect, discarded pieces of very serious, very precise engineering and turning them into something with zero stakes, zero specs, and zero purpose except making someone smile for thirty seconds on their way to the bus stop.
