My son wants a CHIMP for Christmas.
Not a chimpanzee. A CHIMP. Basically, a rear-view mirror for the geek set. CHIMP is a recursive acronym, meaning CHIMP Has Invincible Monkey Powers.
I don't have a CHIMP.
I have a baby mirror, and I have a webcam. Both serve the same purpose, which is giving me a visual indicator of motion behind me, so I don't have to be surprised and scared when someone comes up to me.
The pic of my desktop (and no, my walls are not nearly that yellow) comes from my camera phone, which appears in both the mirror and the webcam.
