What's up, everyone. I'm using this cool little iPhone app called 'WifiPad' (free! on app store).
http://www.wifipad.com/It allows you to use your iDevice as a mousepad, trackpad, keyboard, gamepad, and much more, depending on how people make thier gamepads, which brings me to my next point: You can load custom pads and download them for free from the site.
Now, I'm working on a wifipad that's for use with Anim8or, and I'm wondering what features you guys would like to see in it if you were to use it. Remember, I have full control over what keyboard buttons, mouse, anything you want, multiple-keys-at-once included. Just ask in this thread, and I'll get started right away!
