Ask HN: How do you customize TextMate?

I recently got a macbook pro, and got TextMate. Will be doing some RoR development, and am a little disappointed by the stock display styles that come built-in with TextMate.

I noticed that the theme I always see in code snippets all over the web, typically dark/black background with pastel color fonts (e.g. the one on http://www.macruby.org/ right now) are not installed by default.

The Sunburst theme is the closest I have seen, but it doesn't quite hit home.

Firstly, does anyone know where I can get that TextMate theme that is so popular ?

Secondly, what other suggestions do you guys have for good themes that are easy on the eyes?

P.S. I know I can customize it manually, but that's a pain to do.

Please help.
