I used to love TextMate's Twilight theme. The latest VimCast, http://vimcasts.org/e/25, linked to a utility for converting TextMate themes to Vim colorschemes, http://github.com/sickill/coloration, so I'm trying it out. I had looked into porting Twilight to Vim before (and vimscripts.org has a couple of attempts at it), but ran into an impedance mismatch: TextMate colors (can) include an alpha channel, which Vim doesn't handle, so you don't get a true copy. Somehow, though, these results look pretty sweet. I've also used http://shawncplus.github.com/Vim-toCterm to provide 256-color terminal support, although, while the result is reasonable in itself, it (understandably) doesn't seem to recreate the subtlety of the original. Enjoy!
