I remember this as one of those fuzzy childhood memories.  In
fact, I was never sure that it actually existed until reading
this message.  I know I only had a few minutes to play with it,
sometime in the 70's.  I remember asking "what do you do when the
energy runs out?" :)  I thought it might have been developed in
the aftermath of the "energy crisis" in 1973.
I can picture the wooden frame, and you could see some of the
circuitry through the front I think...
I hope someone finds a picture of that thingy.
