Thanks for the link. It is amazing how far technology has progressed. To think that it took a WHOLE PC to run Windows/DOS and now it can run (pretty well) in a scripted language hosted by another app. I took a look at the source of one of these JS emulation projects and it is amazing the level at which it works - pretty darned cool. I played DOOM in a browser a few years ago - worked better than my 486 of yesteryear.
I'll bet if I looked I'd find one as a VBA macro in Excel.
