dead brains don't dance

I was cleaning the cathair and grit from my mouse innards when ramtops offered me her USB optical rodent, as the Apple mouse will do her fine on the very rare occasions she doesn't use her artpad.

So. Time to venture under my desk for cable surgery.

This is what I found lurking in the far corner... For reference, the pillar is ¾" in diameter. Sorry about the blurredness; the Pro90's autofocus doesn't in low light (and neither does its LCD viewfinder), so this is the best of a bunch of full manual shots, prefocussed in relative daylight, pointed through the cable-strewn gap behind my computer, and with the flash partially blocked by my fingers else the image was overexposed.
