Anyway: slightly different thread: Has anyone tried the summer mapping contest winners yet?

I've tried edifice which i thought was really good. Brilliant use of objects.
The infinifling one is ... okay. I'm sure theres an issue with momentum there somehow though where you end up coming out of a portal faster than you ended up originally going in and gaining energy from nowhere. I'm sure E=mc^2 comes into it somewhere!
The winners one was quite good. Needed a bit of thought about portal placement and order although got confused at times about where i was meant to be going.
