First, "Notebook," a video of a world in which paper and books are computers, in unexpected ways. What you draw is what you click on. It's more art than engineering, and I like the whimsy, especially the toaster.
Second, a wonderful new game you have to play to fully appreciate. CrayonPhysics Deluxe is remarkable. The demo video might look too good to be true, but it really does work exactly as shown, and I found myself grinning a lot as I played. Great for kids and casual gamers like me, it's forgiving, mellow, and can be played in short chunks. And I'd rather be playing it right now, to be honest! (I gather the iPhone version is not so impressive. You really need to be able to draw and immerse yourself in the screen world for this.)
Last was a video I re-ran across while looking for some tips on animating stick figures. I pretty much stopped wanting to animate stickfolks after watching it: in case you haven't seen it, it's Animator vs. Animation. The sequel (Animator vs. Animation 2) is even more extreme, because the stick guy takes on the entire Windows OS. Satisfying!
