I went to the Cool Product Expo at Stanford, mostly to take a look at NeuroSky's innovation. They have created a device that measures the electrical activity of the brain's neurons and combined it with a computer game. Quite cool.
Except Neurosky's stuff, I also found other interesting things, which I also wrote something about. The picture to the left is Kurt A. Kulmann, showing how to clean water with help of UV light.
While at the expo, I met Zamir. He made a nice movie - be sure to take a look at it. I also made a movie, not as good as Zamir's, which I produced in my room at Cardinal Hotel in Palo Alto...
