OK, so, my wife bought son a tiny etch-a-sketch. I, of course, being me 
picked it up and began playing with it. Also, being me, couldn't get the 
constantly running thought out of my head: Vector Graphics and servos.

Now, here's the question. Is there available a hobbyist servo drive 
system? Communication via TCP/IP a plus, but not necessarily a must I 
still have serial ports, and USB is no problem provided it has good 
Windows drivers and a usable API. Would be great fun to transfer vector 
graphics from some vector format to an Etch-a-Sketch screen. ;) Just 
need a way to couple the motors to the knobs, and mount the thing. Bonus 
if the assembly is light and stable enough to just flip and shake w/o 
having to remove the toy.
