Well, that's a good question...The illoz stroll is a completely random way of wandering around and looking at illustrations here.
The stroll is not an intelligent creature at all. It will select one image from each contributor, without a value judgement of any sort, and show it to you.
If you keep strolling, you'll eventually see an illustration from each really good person here, at which point it will start all over and show you other sublime images from these excellent people.
