So I'll get down voted for this but it needs to be said: this is very cool and is a great proof of concept for the direction things are going. However, if you're promoting a commercial product, event, etc., you could have just used flash--it would be trivialish to implement, perform better, and have no cross browser issues--although no iOS to be fair...<p>As it stands, how many people will hit the site, see it's not working because they have the wrong browser version, and leave?
