I think its actually a v.good idea - i tried it once with technic lego (yes
I AM that cool) and it seemed to work quite well, except you can get arcs
and stuff to the lego bricks - im sure if you used fibre optic cable (like a
minidisc type cable) and pulse modulated a laser and then set up some kind
of phototransistor circuit you could get it to work quite well!
