Today’s a day for sharing the puzzly wealth, so I’ve got a few links for your perusal.

First up is this terrific article from IO9, recommending a number of science-themed apps and games with some seriously crafty puzzle elements to them.

From RNA molecules and gene structures to brainmapping and animal classification, these will fascinate AND inform you all at once. Marvelous stuff.

Next up is a great post by Dan Markowitz on McSweeney’s Internet Tendency, exploring what Rube Goldberg could have created if he was a little more petty and meanspirited. It’s Rude Goldberg Contraptions!

A series of dominoes fall, knocking over a marble that rolls off a ledge, landing on a seesaw that tips downwards, dangling a piece of cheese in front of a gerbil that runs on a hamster wheel, unfurling a roll of toilet paper into a trash can, leaving an empty cardboard tube in the bathroom that you’ll have to replace even though you weren’t the person who used it up.

And finally, a little something for the puzzlers in the audience who like some magic and swashbuckling in their solving. The creative titans behind Dungeons & Dragons are filling the gap between now and the launch of their newest system (D&D Next) by releasing dozens and dozens of out-of-print and retired modules, sourcebooks, and adventures from earlier editions of the game.

You can relive some of your all-time favorite dungeon romps, riddles, and puzzle traps at D&D Classics — they’ve already posted the first edition classic The Temple of Elemental Evil — and any you can’t find there, you can probably track down in downloadable form at DriveThruRPG.
