Just tapped a bunch of dust, grit, and I-don't-know-what from my keyboard

I'll use a vacuum on mine every now and again. Mostly dust (expensive electronic filter notwithstanding) and cat hair. He likes to sit on my lap in the evening and distribute his daily growth to the environment.

Right now it's due for a good washing. I really don't think my fingers are that dirty but the keys tell me otherwise!
