Arduino LED Matrix controlled over Bluetooth by Android Telephone

I hacked a little app with google app inventor to controll an arduino over bluetooth. Sketch and app inventor "source" are here: http://arduino.cc/forum/index.php/topic,81743.msg615701.html

I used the App Inventor. There is a canvas indeed. The LEDs are Images which I change when a touch event points to them. For communicating I just send a very simple Code like A+byte to switch on "byte" LED or C+"byte" to clear one. Then there is also a clear all command, you can see it in the last seconds, the arduino clears all 64 LED in a fraction of a second, the App needs some more time ;-)
