Here's a mini compilation of a few fun clips I had laying around.
Let go of the cube underneath you and then as fast as possible, grab it while at the same time pressing the jump key repeatedly as much as possible. (You could bind jump key to mouse wheel or use scripts. If you'd like to try it with scripts I recommend using DemonStrate's AHK script; Portal Wall Jump script: sourceruns.org/index.php?topic=339.0 Although made for Portal 1, it should work pretty okay.) With some luck, you can jump with a cube several times as it works as a "platform" for you. You have to have quick, and just the right movements for this to work as well. I noticed that swinging your cursor down and back up again while letting go, and grabbing, makes for best results.
I think the slow-mo works as a pretty good tutorial but overall it takes a lot of practice. You have to have a wall to lean against, so that the cube can't run away from underneath you, and I noticed you should jump just a tad away from the wall after each jump and then return leaning against the wall for another jump. So basically, you're making a little curvy path as you make several jumps. You also have to face against the wall a bit when making a jump.
In continuous cube jumping you also have to take the cube further away from yourself after a successful cube jump, and then again quickly bring the cube under your feet again, let go and grab.
Even with hours of practice, this is very difficult.

I decided to rerun this challenge by recording with Fraps. This run uses ABH/AFH.")
