About ten minutes to deadline, so nothing long or profound tonight, just a link via 2 Blowhards, to this. Be sure to scroll down when you go there, to see others besides the relatively dull cube.

These are always good for an hour's fun and profundity.

I'm off to read the piece on evolutionary biology.
