Crabfu Steam Toys Artist I-Wei Huang spends a lot of time tinkering with erector sets. And sprockets, and pistons, and chains. Inspired by "the spirit of steampunk," Huang breathes life into miniature "steam creations," and what he designs huffs and puffs and lurches forward on its own. This site not only shows off Huang's diminutive engines, but details every step in their making. Depending on your familiarity with such talk, some of this may veer into gobbledygook ("So I ended up using a mamod boiler with superheater"), but no matter. The photos and descriptions just set the stage for disarming video of the machines on the move. We particularly loved the Steam Walker, which reminded us of the maniacal marching pants from the Wallace and Gromit film "The Wrong Trousers." (in Collecting)
