Full steam ahead!
This steam-powered walking robot makes me happy. Lego’s programmable robotic parts are lots of fun and very popular; someone should make a sell a big set of erector-set-like parts designed to make use of steam power, with various sizes and shapes of boilers and engines, and nifty little spinning valves and steam whistles and stuff. I’d love to play around with making my own steampunk-inspired gadgets, but I don’t have the metalworking equipment or know-how.
