Simpless
One of the biggest reasons I chose LESS over other CSS pre-processors, was LESS.app. It processes LESS syntax into CSS on my Mac, every time I save a file. No Javascript and most importantly no complicated Terminal, Ruby malarkey. Simpless is a compiler that works on Linux, Mac OSX and Windows. I’m testing it now.
I’ll be writing a proper entry about how and why I use LESS soon.
