I make a project, where you have an app that can read a QR code and run the QR code in sandbox enviorment. Basically, this would be something like dwitter, but it's code focus wouldn't be limited to graphic demos, but small games. The problem is to make the most efficient use of space, while having as much functionality. I am basically creating something like assembly code, but can get touch positions, draw on screen, play sounds and etc. Any help how to tackle this would be appreciated. Also if there is more appropriate place to post this, let me know. I am making this on Android with Java.
