Lego Santa Claus, Reindeer and Sleigh

Here's a nifty Santa Claus, reindeer and sleigh made from Lego I found on YouTube. The Sleigh contains a power unit that powers the reindeer via a power transmission axle. The legs of the reindeer are motorized via a worm screw. Most ingenious and compact engineering.

Stilzkin Bridge Launcher

While looking for some fun lego projects I came across this superbly engineered Lego Stilzkin Bridge Launcher on YouTube.




Look carefully, you can see it relies on pure mechanical mechanisms to open and close the bridge instead of using more convenient pneumatics. Most excellently engineered!
