I made a quick demo with browser based and a demo APK packaged with crosswalk.
Curious to know if anyone got Alpha working, if the screen is straight on, it the little pixelly things in the background should follow the angle of the phone - but on export to APK, it appears to follow something else, like the yaw/pitch and not the roll.
In browser, it doesn't appear to do anything.
