Did you ever try to use LED's as an input device?

My next LED cube project will be oriented towards trying to do that.

How do you mean? Like the magnetometer above? LEDs are outputs, no?

Not always, they can be configured to behave as photodiodes, too:

This is also in my "TODO" list, maybe with the next magicShifter revision, or possible once I get the current new design booted and refactored, a bit ..

Ahh ok, you don't mean WS2812s then, just plain LEDs. I don't really have any ideas for what to do with a photodiode, but I have some of those straight LEDs and I really want to make something with those.

What kind of thing would you want to make with LEDs as inputs?
