Howdy David,
I've seen programs that let you build flow charts but one that actually
executes is neat!  Excellent training and programming tool.  With breaks and 
stepping it would be a big help in visualizing a programs flow.  I suppose 
you could also convert a chunk of QB source code into a flow chart version so 
you could filp back and forth.
It would take a heavy bunch of programming to build it.  Not sure you'd be 
able to get your money back out of it when it was ready to market.
