Fleischfilm Films by Thorsten Fleisch, experimental filmmaker. Fleisch "became recognized as one of the world's leading innovators of experimental film with the release of his 16mm film, Blutrausch, a film made entirely from his own blood." "Fleisch feels a compulsive need to attack everyone's eyes and ears... challenging the eyes and mind with wickedly clever films that combine mathematical systems of editing with reflexive commentary." Check out some interviews or Fleisch's stimulating article, Animating the 4th Dimension.

4D rubiks Cube. There's a small (416k) download, but then it's probably the hardest puzzle in the world. It should keep you busy for a few hours.

The Tesseract Charles H. Hinton, eccentric, bigamist, son-in-law of George Boole (yes that Boole) coined the word Tesseract and claimed that we could all visualize the fourth dimension. He wrote several books and claimed to have created a set of cubes that, used properly, would allow anyone to visualize hyperspace. His ideas were all the rage. Salvador Dali was inspired by him. Robert Heinlein wrote a classic short story about a house built as an unfolded tesseract. Madeleine L'Engle wrote a classic children's story. With the advent of Einstein and his claim that "Time was the fourth dimension", the higher spatial dimensions were forgotten. (Until recently that is) And Hinton was forgotten. Or was he? And what happened to the cubes? Rudy Rucker, a huge fan of Hinton,fails to reprint the instructions. Rumours are that, if you build them and use them, they will drive you insane.
