Forget Microsoft’s Surface or the iPhone, a clever Wii hack allows for multi-touch without the touch, similar to the movie Minority Report:

For most applications, touch and touchless interfaces simply aren’t practical. You get tired waving your arms around all the time. Where I dream of using these devices is in collaboration or conferences with a big projector. By pointing at the projector, you can move around slides or digital note-cards to group ideas together, or navigate a presentation by waving at the screen. When working with lots of complicate ideas, the ability to move them around in space relative to each other is huge and doesn’t really exist digitally the same way it does with sticky-notes on a white board.

Some engineers in Microsoft Research have a hack called Soap that’s pretty cool as well if you’re looking for a good DIY project.
