Saw GIF of this but I couldn't figure out just what it was supposed to be doing. Awful lot of monkey motion for a clock, and it wasn't clear that it was made of LEGOs. A little digging turned up this video. Very cool. 

One of the more clever parts was the design of the 11:1 gear reduction. He needed this because of the output speed of the LEGO motor.

I hate to think how much money he spent on this, but I suppose it's like any hobby. If he spent a thousand dollars on it, and then spent a thousand hours building it, that's only a dollar an hour, which is pretty cheap entertainment.

I did not find a parts list, though this video only came out last month. Akiyuki has provided parts lists for other projects, so we may see a parts list sometime soon. The motorcycle kit he referenced costs $230, though you can apparently get the same kit from a vendor on Etsy for $100. Don't know how that works. LEGO made too many? China cloned the kit? They fell off the back of a truck? Who knows, certainly not me.
