There's plenty of fun to be had while at the beach. You can play volleyball, go swimming, or dig a hole, only to have it collapse in on you with high tide fast approaching. Another thing you can do, though, is try to build yourself a QR code out of sand!

QR codes are pictorals that contain embedded information -- usually a URL or a coupon for something. Widely used in Japan on flyers, book bindings, and in other places, it allows you to get more information about a product that you see advertised almost immediately, and bookmark it for later.

According to CScout Japan:

Sinap is teaming up with the Nishihama Surf Lifesaving Club to promote beach cleaning efforts. According to Sinap, the efforts to break away from information noise pollution and to rid beaches of disposable lifestyle goods (plastic bags, foam trays…) are complementary endeavors.

The project is pretty impressive in what they did, especially since a lot of people have reported that they were successfully able to read the QR code on their phone. The trend for QR is just starting over here -- I've mostly seen clothing designers and artists use them, but I figure the trend will follow suit within a year here in the States.

Have any of you started using QR codes on your phones? I know my LG Voyager doesn't support it, but I'd figure any of you with a Jesus Phone would be able to. Also, check out the making-of video after the jump.
