The idea kind of came along when I was extracting Gallery CSS from the project that I built it for — I realised that people probably wouldn't understand the library, or the need for it… but I didn't want the cool tech result to go unnoticed.
Originally it was going to be an ebook… if I'd have done that, it would've been released about 3 weeks ago, but the knowledge transfer is far more challenging VS a screencast.
