Dan Roganti suggests a physics demonstration tool like http://powdertoy.co.uk/ might be connected to a vintage computing demostration, to provide "physics" results from vintage computations or vintage control. That sounds plausible to me. It satisfies Dan's goals of presenting early computing means to generate mathematical solutions on critical problems of the day. And it satisfies visual presentation goals of making those cryptic numeric and physics code, accessible to people without that training. For my techie interests, I'd be curious about how to make the two work together. A modern computing box or tablet, running this program with a Lua API – whatever that is - connected to some vintage box through likely-simple serial-hardware protocols? Can they live together? It's "the odd couple"! ;) Herb
