Hm... just discovered the ondevicemotion event for HTML5. I wonder if I could use that to provide inputs on mobile devices. Looks like support for it is not very consistent yet. But I got a new phone yesterday (LG Optimus T) partly so I could start testing mobile game compatibility/support, and that device can detect motion. I don't know yet whether its browser supports motion events, but hopefully someday if not today. I can't tell what browser the device runs. I suppose there are other browsers I could download. Wow there's Dolphin Browser, Opera mini, Opera mobile, Skyfire, Dolphin Browser Mini, Boat Browser, UC Browser, Boat Browser Mini, Angel, Galapagos, Ninesky (ooh, explicitly supports HTML5 and flash), NetFront Life Browser, good grief, 15000+ results! Why the hoop'n'daddy are there so many browsers!?
