I accidentally got my trackball to flicker different colors when a call comes in. I don't recommend anyone do this intentionally, but thought you all would find it interesting.

I was eating dinner and didn't realize I got some honey/orange glaze on my fingers. (Bet you can tell where this is going!) Later I realized I'd gotten some of this sticky stuff right on the trackball and had been rolling it around! I panicked and immediately cleaned it as best I could without taking the whole thing apart. Now it's just a tiny bit sluggish, but when my phone rings the trackball flickers different colors! I'm still worried that the trackball will stop working, but for now it's pretty cool!
