I believe that the dragons are widgets, they're not really hyper links but they do come from other sites. They're like a mini program.
Most people that have widgets here now are the ones that have them in their signature that keep track of how long it's been since they've had a drink, for example, and it is keeping track in real time. Changing before your eyes. Other widgets you have to click on to activate.
There are widgets out there for just about any interest. I was at
www.abc.com at their Lost sight and you can get a Lost widget. That one will play like a commercial for the show that changes each week.
