I gave a short talk on CAL at the Vancouver Eclipse Demo Camp 2010.
For those blessed with a copy of Apple Keynote, the slide deck can be
downloaded here:

Be warned, this file is rather large (at 102 MB), mostly because it
contains a number of embedded videos and a flash animation of lambda
reduction.
A PDF can be downloaded in lieu of the actual presentation (at a mere
12.1 MB!):
