A fair bit of time has passed since EGX Rezzed but I wanted to mention a controller I saw at the show. It’s made out of a shoe tree and forms part of Robin Baumgarten’s one dimensional dungeon crawler, Line Wobbler.
Line Wobbler plays out on a 5 metre LED strip. Your job is to move the green blob to the far end of the strip without hitting either bright orange bits (lava) or red blobs (enemies). Enemies can be killed by twanging the shoe tree spring to make it vibrate. Getting to the end of the strip means you complete a level and are returned to the start of the strip for the next part of the challenge. All in all there were nine levels when I tried it. Here’s a video so you can see it in action:
