Now that I have my first app created, I wanted to get my foot in the door with games. The idea I wanted to work on first incorporates turning the screen into a doodle pad. I was just wondering what kinds of things would be good for that. I'm pretty good working with views and such, but couldn't find anything on Google for making a doodle pad.

The game would kind of be like Pictionary where a player has a certain amount of time to draw something for another player to guess.

I know this may seem kind of broad, but I'm just looking for some ideas I can work with. Any information and suggestions are greatly appreciated.
