As we know, Julian Beever is an international well-known sidewalk chalk artist whose drawings have appeared on the streets of London, Buenos Aires, Paris, New York, and countless other cities around the world. Beever creates drawings that look completely three- dimensional when seen from the correct angle.
Now, in his book, Pavement chalk artist: The three-dimensional drawings of Julian Beever, the artist shares some of his most fascinating and humorous pieces, Here are a few examples you’ll find in the book.

●Philadelphia eagle
In Pennsylvania, Beever created “Philadelphia 
eagle ”a huge drawing with an eagle landing 
successfully on an American national flag.
 

●Meeting Mr. Frog
“Meeting Mr. Frog” was created in Salamanca, Spain, and is about a realistic-looking frog sitting on a Lily pad.

●Swimming pool in the high street
My personal favorite is “Swimming pool in 
the high street” from Brussels, which is about 
a woman relaxing in a swimming pool-----a swimming 
pool sunk into the middle of the street, that is!
Along with an introduction about his background, Beever includes a description of the techniques he used and the challenges he overcame with every drawing. He shares information about his time at home in the UK. and abroad; there is a fun story to back up each piece of art.
Beever’s artwork is truly jaw drooping. You’re sure to spend ages turning the leaves back and forth, surprised at how one man can create what looks like a three-dimensional design on a flat surface with just a bit of chalk. From animals to superheroes to famous buildings, the paintings are a wonder to lay eyes on.
＊Payment chalk artist: The three-dimensional drawings of Julian Beever is surely worth a look. And another look. This 112-page hardcover book is available now from Firefly Books at a list price of $ 29.95

People are being lured (引诱) onto Facebook with the promise of a fun, free service without realizing they’re paying for it by giving up large amounts of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.
Most Facebook users don’t realize this is happening. Even if they know what the company is up to, they still have no idea what they’re paying for Facebook because people don’t really know what their personal data is worth.
The biggest problem, however, is that the company keeps changing the rules. Early on, you keep everything private. That was the great thing about facebook — you could create your own little private network. Last year, the company changed its privacy rules so that many things — your city, your photo, your friends' names—were set, by default (默认) to be shared with everyone on the Internet.
According to Facebook’s vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don’t share information, they have a “less satisfying experience”.
Some critics think this is more about Facebook looking to make more money. Its original business model, which involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they’re online connecting with their friends?
The privacy issue has already landed Facebook in hot water in Washington. In April, Senator(议员) Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set guidelines for social-networking sites. “I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them,” Schrage admits.
I suspect that whatever Facebook has done so far to invade our privacy is only the beginning, which is why I’m considering deactivating(撤销) my account. Facebook is a handy site, but I’m upset by the idea that my information is in the hands of people I don’t know. That’s too high a price to pay.
