In case you've been living under a rock, there's been a new phenomenon taking place at the World Cup, a tradition unknown to us, which is the vuvuzela horn. Need more? See this Discovery story on it and you'l be caught up.
The other annoying fad is replicating that aforementioned 'experience' on smartphones. The iPhone has 'em, Android has 'em and yes, now Windows Mobile.
JDB software has made a freeware app (like anyone would pay for this function) and it's actually pretty top notch. It works on all WM6.x touchscreen devices, all resolutions.
The UI design is very-much Windows Phone 7, which we like. You also get choices in the size of the horn and sound-type (traditional or euphoric) as well as skinning the horn with you're country's colors, 'cause nationalism is still very en vogue these days.
Probably the most, dare we say, fun part is the ability to play it by traditional screen-tapping or by blowing in the microphone. Okay, that's kinda cool.
Grab it here and apologize to your friends/family for us in advance.
