Following the recent discovery that the T-Mobile G1 did have the hardware capability for multi-touch gestures, Ryan Gardner has created a hack that makes use of the commands from the debug logs.  The proof of concept video shows the hack, which draws a red line to register the first finger, and a yellow line to register the second finger.  By dragging both fingers along the screen, two lines, of red and yellow, are drawn wherever the fingers touch.

As seen in the Apple iPhone, there are various applicable and valuable uses for multi-touch in various applications (most commonly seen in Safari and Google Maps).  It will be interesting to see how HTC and Google respond to this most recent hack, considering that the Android platform has been heralded for being open to all applications.

Check out the video after the jump.
