Around this time last year a helped a fellow who was creating a small Flash demonstration of his rather complex and sophisticated online sailing simulator. (Very well modeled physics; competitive sailors use it to practice tactic and strategy.) What challenged us was “not too easy, not too hard”; the demo had to give a taste of the regatta’s subtlety without turning folk off.
It just occurred to me that such a demo might be useful for EteRNA. And it would make sense as a FB gamelet!
p.s. maybe this could serve as precursor for app?
