This is a tmTheme for textmate which also works on Sublime Text 2.
It is inspired by the Visual Studio theme Son of Obsidian which also is inspired by Eclipse Obsidian.
I am unsing it mainly for html and javascript, feel free to enhance and send me the changes.
Download the file or install with Package Decontrol:
jfromaniello/sublime-node-require
I don't know but it might be something like:
~/Library/Application Support/TextMate/Themes
