C.R.A.P. design principles

a while back, i had a lovely link to a teaching resource on the C.R.A.P. design principles as asserted by Williams and Tollett. that link is no longer active, but thankfully Presentationzen has a lovely page. i'm linking it both here, and below (under "tech, text, and design") but wanted to call attention to it in a brief post (said post also acting as a nudge to start posting again).
