I have noticed the handstand push ups is a big part of the crossfit workouts.Now I have seen photos of people doing these or videos, but some part of me believes they are not really humanly possible-despite the evidence to the contrary. The crossfit mainpage had some variations so that you can work yourself up to doing these "beast". I have been doing a variation where my feet are up in the air on a bar help up on a squat rack. My version is more like an almost vertical incline push ups yet I know that the real thing is way harder to do.
