Something fun for you to try...
 

Remember that level editor I posted up on the projects? I just made a level in it. Run the level editor with the files smw.colors, smw.tracks, smw.catalog, and smw.level. Scroll down to find the island-like level. Ok, here's the challenge. Implement the level. Animate the characters, etc. You are free to use any graphics/sound library that you wish and any language that you want for that matter. I don't care. Post your code here where you're done.

Post code? But I thought you were against the idea of posting code?

What?
