Okay, I think I might have seen this done once before, so I thought it would be cool to do again. Here's the deal. I will post a demo here that is 2500 1000 frames long (give or take a few frames), and then you guys will make a map that is completable using that demo. In other words, it's like a DDA, except instead of the player making the ninja move using thwumps/launchpads/trapdoors/etc., the demo makes the ninja go through the level.
Moving on, this is, in a way, modeled off of Paradigm Shift. The best author who makes a map using that demo after one week (according to the winner of the previous week), now makes another 2500 1000-ish frame demo and another week begins. I figure a week will be sufficient time to make a map, if anything comes up or we decide it's not the right amount of time, i will change it.
I'll also keep a list of winners, and might include a list of contestants if it doesn't become to troublesome. You don't need to sign up anywhere, just post your map here.

Alright, well, good luck! (By the way, it is probably a good idea to have the map you make get ALL of the gold. It's not necessary, but it will improve the judge's thoughts on the map IMO.)
Btw, i tried some sigbars for the winner:
