The picture is a 2D barcode, so it’s like a regular barcode but can store more information — up to 250 characters of text in this case. The one pictured encodes a message from me about printing such a barcode on a T-shirt, and if I did, what slogan should it be?
The barcode can be de-coded by a anyone with a mobile phone, using the camera and barcode scanning software. Sometimes they are used to get URLs or contact details into phones — you could print one on a business card, for example.

libdmxt doesn’t seem to extract anything from the image, which surprised me.
Ooh, on a related note, have you scanned the Google barcode?
Code_128, text.

The Wikipedia page about this particular type of barcode is informative.
