Try this one. It also has some Markdown themes. Many themes there are optimized for Sublime Text, but should for in TextMate too.

I would also like to see some kind of visual theme/grammar editor built into Textmate. I’m not a programmer so creating a theme or a new grammar isn’t easy for me (if not impossible). I’ve been able to modify some themes, but it would be nice to have a simple GUI (possibly with a feedback window of sample text) so I’d be able to even create themes for a new language without knowing the crazy grammar syntax (or even a new grammar for that matter). I’m sure it would be an involved process, but definitely worth it to me, even if it slowly grew over time. It would be nice to have simple options in a UI, and maybe even the ability to place your cursor in an open file which would allow you to edit the highlighting for that part of the grammar.

On a related topic, I’d love to see an enhanced Markdown theme (if one doesn’t exist). I’m using Markdown more and more for general notes and some html. Would be nice to have some highlighting for bold, em, links, lists, maybe even variations for # heading levels, tabbed indents for heading levels and associated content, etc.

thanks
