Maybe I should answer that, seeing how I put them there :-)

They are called QR (Quick Response) Codes. The Wikipedia page (http://en.wikipedia.org/wiki/QR_Code 
) will tell you all you could want to know about them.

Basically, if you have a smart camera phone (Iphone, Android-class  
phone, Blackberry etc.) with a QR reader app installed, the phone will  
scan the code to extract the URL, email address, phone number, or  
whatever the QR code happens to contain. Then the phone can use that  
to jump to the relevant web page, etc. It saves a lot of unnecessary  
typing, and is quick, hence the name.

The previous version of the cheatsheet had a page full of web URLs,  
which can be a pain to type. Most of these are on the Wikipedia APRS  
page, so it made sense to just have the addresses of that page, plus a  
few other key sites. The QR codes were just for the convenience of  
those with the necessary gizmo to read them.
