I ran across this article on how IdeaPaint got started. Another great college student(s) solve a problem and make a boat load of money at it.
But why to I bring this up? Simple, if you were to add the eBeam product to this wall, all of that great artwork, plans, world domination schemes, details, flow charts, etc. etc. would be captured onto the computer.
Once there you can manipulate, change, delete, add, save and distribute the information. You can even add pages to it after you're done so that the whiteboard work you are doing now becomes more of a dynamic growing document - how cool is that.
eBeam helps take a great idea and make it even better.
