Years (er, decades) ago, while in college, I was tasked with hooking up a primitive stationary bike with a virtual reality headset. The CRT monitor no longer worked for some reason, but the bicycle itself was still sending out signals, similar to the original story. The university was big into VR and graphics, and had developed a VR SDK and headgear. Hooking them up was a fun task since I got to work with C internals, connecting things at a lower level. It actually worked quite well. Today I work on systems that deal with large queries per second, but almost not as fun as getting your hands dirty with low-level bytes.
