Hey all. Came across this promising app. It's an Android app that will allow you to control your reprap from your phone instead of using a computer as a host. Very handy when your significant other would like to use the lap top while you've got a job running.

It is also able to simulate what your gcode will look like. Allowing you to check how your print should turn out, making it easier to spot errors and fix them instead of wasting precious filaments.
Unfortunately it doesn't run with my version of Android(2.2.2) but looks like really cool work.
