Clearlooks2-squared ,with a cherry red close button and left-aligned window titles, not to feel more like a certain operating system's official theme, but because it looks really good and marks the close button as a potencially dangerous one. Plays nicely with clearlooks gtk themes, and tango based icon themes (specially tangerine).
Based in clearlooks2-squared (by.. uhhmm.. I have to look up) and Clearlooks With a Cherry on Top (by NaCI)
I want to change the icons inside the buttons to something more like the ones in more-industrial, I think those are more clearer. unfortunately, I don't know how to do that, so if you know, let me know
