Today, is all about visual:

• from a study on biological motion patterns, play with the sliders here and try to guess who's walking;
• adverstising companies should take a look at the heliodisplay, it can really boost any old billboard;
• a truly "fingertips" experience with this new computer interface, TactaPad, and since i'm only linking to visual experiences, watch the demos where one interacts with a Mac, and where one makes some drawings;
• and finally, a personal site which looks exactly as is owner powerbook (requires flash player 8).
