(edit - created web-sphere repo; also added DaVince so he can get his CanvasSphere stuff onto it as 'canvas' branch or something; enjoy!)
Small update: I just had a while( true ) game loop running in the browser Web workers are doing the trick ^^
function game() { while( true ) { // render }}
function game() { // init}function game_update() { // render}
FYI Radnen, I just tried the demo app from your link on my HP Touchpad tablet running Android (unofficial Cyanogenmod 10) and the 'touch' event doesn't register as a 'click' event and 'swipe' doesn't analogue to arrow keys or anything like that. For the web engine we may want to consider handling tablet/smartphone input methods as well as standard inputs.
