If you’re a data and/or gadget junkie, or you know someone who is (and they’ve already got enough Ambient Devices), infosthetics has put together a guide to 20 info-centric gift ideas—like this $29 poster that maps the “genealogy of pop/rock.”

We personally like the Lightspace Design Display System, which turns your entire wall into a pixellated, glowing screen (it’s the one item on the list without a fixed price, naturally). Another great one is the jack-of-all-trades chumby, which just recently went on sale—and if you’re budget-conscious you can just set up a virtual chumby for free and be a vicarious consumer.
