I am working on a remote control steerable version. I still have some work to do, im on prototype #3.
I am using WowWee dragonfly guts!

ouch!, how could I've not remembered this before?!?!

There was a Spanish block game called Tente, that sold boxed pieces with blueprints to make ships (they added some special blocks for cannons, the bridge, the front, and other not blocky parts of the ship but most of the pieces were pretty standard) and one or two of the pieces on each box was like a vibrating toothbrush with a battery holder and a switch that was used to make the ships "sail" on the floor (I recall having some of them when I was a child, like 20 something years ago, I think I don't have them anymore).

I don't thing it's very difficult to replicate this with LEGO bricks to give the little bugs some of the LEGO sex-appeal XD
