When I first found the Worth site via a link to Scary Signs (I think it was about the third or fourth in that series at the time) it was easy to go back and look for one I might want to link to, to illustrate a point. By the time I really wanted a particular sign, the site had grown to the point where it began to be difficult just to find the right series of contests.
It's become an interesting maze of cleverness and artistry, and almost impossible even to explore without getting lost.
I've had problems with the Google links a few times, but usually if you go to the site after Google tells you where it is, a direct link is a little more reliable. For text seaches you usually can just click on a "remove frame" button, but that feature doesn't appear in image search results.
As always, it takes a little time and effort to "do it a little better," so trying the Google search URL first usually works for most. I don't mind doing a small rework for someone who reports a problem, if the complaint seems reasonable; but usually it's pretty hard to tell why a link works for most but not for the few. I don't often bother looking for a reason, since an alternate link is simple (usually).
