Line Wobbler isn't how most gamers picture a dungeon-crawler. It's a long LED strip stretching down from the ceiling connected to a spring-based joystick -- more installation art than video game. Its developer, Robin Baumgarten, didn't expect his niche little project to gain much traction in the gaming community. A physical thing, a few dozen copies of Line Wobbler exist, but its reputation has far transcended the limits of its hardware.
