I said in my post about the Vuvuzela app that I’d post the source separately and promptly forgot to do so until reminded by an anonymous comment on my original post. Since then I’ve made minor tweaks to enable touch gestures (manipulations). It’s the updated code I’ve uploaded.
Great, just in time for the world cup! oh wait... nevermind.
Realistically I didn't think anyone would be sitting in front of their telly running the emulator on their laptop just to add more Vuvuzela sounds to the action. Maybe I misjudged it though :) Mike
