I posted this in General Discussion forum under a probably too cryptic name, and it's gotten NO views yet.  So let's try this again with a better description, give it a look. 
1/150 scale RC tractor-trailer
This is a very brief build video of a 1/150 scale RC tractor-trailer.  I believe the tractor is controlled via Blue-tooth, and the trailer has an IR connection to the tractor.  The title of the other thread was "Watch making at a whole 'nuther level", which really describes what this guy did.  Not many people can/will build their own micro-controller board by mounting a surface mount chip upside down on a piece of perf-board.  And he added functioning lights, at this scale.  Just the wire size alone is mind-boggling to me.
I particularly liked the 180 degree turn over a lap-top touch-pad at the end of the video.
How about a standing Golf clap ovation for this guy?  He deserves it, whoever he is.
