You have probably seen Apple's multi-touch interaction method used on the iPhone. It is really amazing. When you combine the power of the most accurate input device in the world (your fingers) with multi-tasking input, the result is a very natural and organic interaction flow.

This stuff is really amazing. There are so many possibilities with this.
