There's been a creationist or two lurking around on the blog recently*, blathering about complexity. So I'll take the opportunity to drop in a favourite video from QualiaSoup on the topic of irreducible complexity.
Of course, ID is dead, but that doesn't mean this isn't still a fascinating video.
* the two creationist respondents "John" and "Marc" posted from strikingly similar - though not exactly matching - IP addresses, both owned by the same ISP. I suspect they're either the same person or else closely allied. Or it's a coincidence that they're coming from the same IP block.
