Ocarina

This app actually turns your iPhone into a wind instrument. You blow onto the mic to create a sound and there are four 'holes' on the touchscreen that create the different notes. It has a really nice sound and is quite addictive trying to learn how to play a tune. I worked out how to play 'Happy Birthday' this evening. I now need to learn some Christmas Carols in time for December.

The photo shows the 'World View'. This shows where other people are playing their Ocarina around the world (via the GPS in the iPhone) and lets you listen!
