I use <a href="http://github.com/jamis/fuzzyfinder_textmate" rel="nofollow">http://github.com/jamis/fuzzyfinder_textmate</a> which is an extension to the existing fuzzy finder vim plugin which tries to simulate textmate's fuzzy finder file opener (cmd T if you're on a mac). It's really quite awesome and I use it every single day, all the time, to open every file I work with. The downside is that you have to use an old version of the regular fuzzy finder gem because the guy who maintains that gem changed the api a bunch of times - to save you some trouble I believe the correct version of normal fuzzy finder (<a href="http://www.vim.org/scripts/script.php?script_id=1984" rel="nofollow">http://www.vim.org/scripts/script.php?script_id=1984</a>) you have to use is 2.16.
