Once upon a time, there was a club called CAS (Caltech Anime Society), which as you can imagine was associated with Caltech. That worked out pretty well from its founding in 1992 until December 2011, at which point there were some issues with the club having too many non-students and not enough students at certain meetings. Not that Caltech minded, except for the fact that campus meeting space and other resources were being used.
Thus, the Power Puff Girls were born! Err, sorry, PCAS (Pasadena Cartoon and Anime Society, or if you prefer just Previously CAS), which is a club for us to continue showing anime and maybe the occasional Venture Brothers episode or something, only not on campus. That doesn't mean we want to exclude Caltech folks - quite the opposite! If you're interested in attending let us know - our showings were always free and open to the public, and so far we're looking to continue that tradition.
We arguably started meeting the weekend of December 9, 2011. Our first regularly-scheduled showings take place January 27, 2012.
