duh?

I continue to have n00b questions like:
"how does the stuff stay on the table?"
and
"can I draw a picture on the table and have it follow it?"

hmm... now that's not a bad idea.
a line-follower.
we can do that. I bet we can, with enough contrast and a simple calibration tool.
!!!!!!!!!!!!!!

ooh!
and an overhead projector that puts a line drawing right down on the surface! no tool paths!
instant scaling! sketch it, route it!

look what you've done...
