Got an immorally excessive amount of free time, and a good helping of patience to boot? Then peep the video after the break. We fell asleep a full three times watching the 1:44 video of David Wegmuller's Lego "self tracker," but that doesn't mean we don't recommend you give it a look yourself. The machine is basically a souped-up "train," which can place its own track, Wallace & Gromit style. The sluggish bot rolls onto a freshly lain track piece, and then turns to grab the one behind and swing it around in front. We're impressed greatly by the total lack of utility and all-around foolishness / ingenuity of the project, and can't wait to see what David brews up next.
