|QR Code Periodic Table of Elements|
So you've seen those strange 2D bar code-like things that are appearing all over the place. As you may know, they are called QR codes. With the proper application on your smart phone you can read the codes and get information such as a web site, location, phone number or message.
Well, these folks took the QR codes and created a pretty interesting periodic table with them. There is a QR code for each element or the periodic table, and each QR code encodes a URL to a video about that element. I've only looked at a couple so far, but they look pretty interesting. (See their whole site here)
To try it out, click on the image above to view it in full size and point your smartphone camera at it while running a QR decoding program and you should be taken to a different element's video for each one you decode. Try it out. Its fun!
Who can tell me what is encoded in this QR code? Answer in the comments.
