Friday Links: Steve Jobs, Brain Games, and Led Zeppelin

The Onion's fitting tribute (NSFW) to Steve Jobs.

National Geographic Channel mini-series Brain Games, premieres on Sunday, "using interactive experiments, misdirection, and tricks to demonstrate how our brains create the illusion of a seamless reality through our memory, through our sensory perceptions, and in how we focus our attention."  Some games and illusions on the site, and a companion book, too.

And finally, going out to all those folks who played cassettes ("Does Anybody Remember Cassettes?") of Led Zeppelin IV in their cars during the mid-80s, a tremendous mash-up of "Black Dog."
