I was told about this app called Kainy for android phones. Its a optimized remote desktop app that also allows you to customize a gamepad / joystick and button overlay. The buttons can have assigned functions or linked to keys on a keyboard. I thought this would be cool for people with robots that have the PC onboard or if you want to use your phone as a remote controlled instead of holding a whole computer and game pad. It works on 3g, 4g and WiFi. Its on sale for 2.99 on the play store right now.

Here is the multiple screen project Which I'm sure Aameris will like:
