Paint by Phone

Use your mobile phone to go to http://www.dodgeball.com/move then use the numeric keypad to control the cursor on screen. (If your phone does not have a web browser, I suppose you can use this.)

How it works [source]
This Director file is constantly looking at a text file (lingo.txt) located at dodgeball.com. As the user presses buttons on their phone, the text file is updated with the last button the user pressed (which translates into the direction - up/down/left/right) as well as a counter variable so that Director knows to move the circle only after the user has pressed another button on the keypad (otherwise, the circle would move in the last direction pressed every time it grabbed a copy of lingo.txt from the server).
