Well, I don't think that particular application is really that ridiculous. It is talking about "multipoint sensing devices". Meaning two (or theoretically more) inputs on screen at the same time.

I guess it's relatively similar to what Apple has on the touch pad:s on some of the Powerbooks. Like two fingers to the same direction is panning, and one finger static and other circling is rotating etc.

I haven't actually seen that anywhere before. Remote User, can you point us towards some prior art touch screen devices that have this feature?
