with a perpetual tile board. I have a very large grid of symbols that needs to be panned (only showing subset in broswer window). The screen is attached to a microsoft kinect UI so the user grabs the tile board and moves it in each direction to show other elements.
My issue is that loading the entire tile board ahead of time is killing performance (naturally). I would like to load / unload symbols as they appear and disppear to the view.
