This is pretty interesting, follow the link and watch the motion of the blue lines, then turn on the occluders..

Technically the mechanism at work here is known as "motion binding". When the edges of the diamond are covered by occluders with the same colour as the background (here, white) there is no information on the vertices of the square. Now the ends of the line become a property of the line and there is insufficient information to detect the circular movement.

거의 매일 들르던 놀이터 같은 곳이었는데... 새삼 문득 갑자기 '가고싶다.'

The Bourne Ultimatum Google Tie-in

The movie The Bourne Ultimatum will be partnering with Google for promotion. Starring Matt Damon, this will be the third installment of the spy thriller after The Bourne Identity and The Bourne Supremacy. The movie site – turn down your speakers if you don’t want sound – reads (case adjusted):

The Ultimate Search For Bourne on Google
Starts This summer

Not sure what this will be about – maybe a game including custom Google Maps where Google is hiding stuff, similar to their Xmas scavenger hunt? NateDawg writes he “noticed a nice little Google Maps logo at the bottom left hand side.”

Previous Google movie collaborations included The Da Vinci Code as well as The Break-Up, and they were all tying into Google products (like Google Video, or the Google Personalized Homepage), so that both Google and the movie got some advertising.

Hooray for Earth Day! People gather to recycle cans before turning around in their SUV to go home. This above photo was a message from the World Wildlife Foundation to China. It reads, "Drive one day less and look how much carbon dioxide you'll keep out of the air we breathe." We think it looks neat and makes its point well.

Useful
G4 teams up with Earth 911 to provide a gadget recycling search engine called Gcycle. You enter your zipcode and the electronic you want to recycle. They tell you where to go.

Clever
LAPTOP instructs us on how to make a keyboard into a wallet, and gives us four other ideas to find new uses for old gadgets that aren't bad at all.

Provocative
WorldChanging takes a stance against Earth Day.

The biggest problem with Earth Day is that it has become a ritual of sympathy for the idea of environmental sanity. Small steps, we're told, ignoring the fact that most of the steps most frequently promoted (returning your bottles, bringing your own bag, turning off the water while you brush your teeth) are of such minor impact (compared to our ecological footprints) that they are essentially meaningless without larger, systemic action as well. The strategy of recycling as a gateway drug -- get them hooked on it and we can move them on to harder stuff -- has failed miserably.

We all know that changing a lightbulb is meaningless if we are building coal fired power plants like mad. The issues at stake will be dealt with at the government level, not in our chandelier... [but] small steps lead to education and awareness and that leads to votes and votes lead to change.

How are you celebrating Earth Day? – Mark Wilson
