So I was just wondering what sort of levels and objects would you all like to make in LBP?

I was thinking of going back and playing various Platformers from the past and and recreating some of the levels. The easiest it seems would be Super Mario Bros. I thin kit would be cool to make a few of those levels down to the last detail. And from the previews shown it looks very much possible.

I also wanna try and make a small bungee jumping type mini game. Tho I'm not sure what the allowed hight is for this game so that one altho simple may not be possible anyways.
