Another cool video for our readership today, this video demonstrated an experimental multi-touch system applied to the Nokia 5800 XpressMusic handset.

The developer apparently attempted to make a kind of Guitar Hero type of game for the Nokia 5800 handset, and he says he faced two challenges. First challenge was the button layout on the screen and the second was single touch tech.

So what does a developer do in this circumstance? Well he overcomes the lack of single touch tech and applied multi-touch tech. So hit up the video below and check it out.
