The animation is brilliant. I think what I like most about your pieces is your choice of style vis-a-vis your story. Which is to say that I think the style of animation (and also the choice of live action for Miasma) did a lot to hold the work together and create an enjoyable piece -- the style itself really helped move the story forward.
If I were forced to pick something to improve, I would chose the acceleration/decceleration of the cans in Duchamp'd when they bounced. It didn't look 100% gravity-driven. (So I'm saying that I couldn't suspend my disbelief about a bouncing can, even though I had no problem with a walking lamp and an acrobatic stool?!

(BTW -- You did notice that on the Cranium page, the last line of text is overlapped by the Play Movie button. At least it is in Safari, but its Flash, so it should be the same, right? Not that you asked for input on web design....)
