Google and bar codes

Don't be surprised if you went on the Google page and thought that you had gone to a wrong place. Google has changed it's logo today to a bar code. I guess it is to commemorate the fact that today is the 57th anniversary of the first patent on the bar code (source).

Apparently, it just says "Google". Were you expecting anything else?

Anyway, I also found out that Google has a open source barcode project of it's own called ZXing which it says is pronounced "zebra crossing". They also have an online QR code generator.
