 I had tried similar code to this on the processing iOS app on the iPhone 4s and iPad 2. Lets hope the same multitouch events can be called by an online implication of the code. 
 
 Update 26/10/12 Whoop! just tried it with my phone and got a different colours for every (additional) finger!!

Share appreciation and ideas on twitter, @nanoBorg88
