Touch screen on mobile demo

[anvaka]

Hi, Rowan!

Thank you for the implementation and very nice demo! When I was on mobile phone (iPhone) I couldn't tell what this library is doing because I was trying to drag the "pin-point" icons.

It would be awesome to have the demo mobile friendly :).

Yeah mobile friendly would be nice although admittedly it's kinda low priority - still got one or two bugs to iron out before moving on to gold-plating :)
