I'm reminded of this silly little microcomputer from the 70's, where all you could do was flip switches and watch lights blink. There was a company that wrote a BASIC for it. Then, five years later, IBM came out with a much more capable microcomputer and that company made their real fortune by selling the OS for it.

The punchline being, of course, that sometimes a toy is just a toy, no matter what you end up doing with it.
