CURRENT STATUS: I'm updating the app to support a device with the ability of lifting the tool.
This app allows you to draw on the tablet touch screen and generates the corresponding GCode to print it on a CNC machine directly over bluetooth. You can see a working example here: http://www.youtube.com/watch?v=dBtlcxkml6k
