That's fascinating. I'm sure the "Sun" would be interested in that story.

What an original use for a BASIC Stamp! I must say, I'm really impressed by
your experiment. Got a good laugh out of it too [noparse]:)[/noparse]
Maybe you should submit it to Parallax... they'll give you up to $150 in
Parallax products if they like it!
