I'm worthless :(

What can I program to test myself? I need something challenging to check whether I really am worthless or not.

Thanks /prog/.

Copy this, but give it some user interface so I can choose some options.  Allowing the user to set the "distance buggy runs before program stops" and "how many runs in one bunch beofre breeding" etc.

I'm on lunix, so decompiling the SWF and re-compiling it would be better than some VisualC# with .net abomination.
