Google's new logo is a barcode which, as far as we can tell, says "Google." Today is the 57th anniversary of the first patent on the bar code. Inventors Norman Woodland and Bernard Silver filed the patent on October 1949, and it was granted, No. 2,612,994 (pdf), on October 7, 1952. The original patent was for a system that would encode data in circles (a bulls eye pattern), so that it could be scanned in any direction.
The barcode on the Google homepage is Code 128 encoded, which is a standard way of encoding ASCII character strings (ie. A-Z, a-z, 0-9, etc.) into a barcode. It would be safe to assume that Google used their own open source barcode project, ZXing, to generate the barcode. The same library is used in Android for barcode recognition.
Google regularly changes its logo for holidays and other special events. Here's their 10th birthday logo from last year, for example. More recently they celebrated Gandhi's birthday. Google hosts some of their holiday logos here, and fan created logos here.
We had to double check that the barcode in this instance was correct (some of the geeks here insist the barcode isn't 100% correct), since Google have previously messed things up a little when they try and talk geek dirty.

Today if you visit www.google.com you will be able to see the logo of Google was changed to bar code. Google was really celebrating the anniversary of the bar code which was patented on 7th of October 1952.
This
special date was coincides with the announcement of the combined
winners of the Nobel prize for physics, who had contribute in inventing
"Charge-coupled devices" to read bar codes. The inventors are Charles
Kuan Kao, Willard Boyle and George Smith.
The Charge-coupled
devices is a silicon based integrated circuit that converts light
energy into an electronic charge. With this technology it has bring
digital imaging technology to a higher level. Some of the application
that we can see today was in digital cameras, CCTV cameras, endoscopy,
desktop videoconferencing, fax machines and lots more.
If you notice, Google
had been celebrating some of the world historic day specially those
that had change our life a lot such as the bar code invention. With the
celebration, we are able to learn a lot of important invention and
important dates. I expect Google will show us more of it and I can't wait for the next important dates that Google going to highlight.
