I am trying to make a maths game. I would like to know if (how) I can halve the screen so that the left window container is normal orientation and the right is inverted. The idea is to allow multi-touch, so that 2 kids can sit opposite each other and both read the labels and graphics. Same GUI, 180 degree orientation on one side.
You ought to be able to accomplish this using a simple rotation animation (example here). Then it would just be a matter of having two views which take up the whole of the viewable area of the app.
