Again Thanks very much for sharing this great piece of art with us.

I have to give this extension 5* because it is very easy to use and very SEO friendly. You don't even have to touch the php or xml files in order to create more icons, because by default it support 20 icons!!! FishEye only support 6-7 by default.
In terms of SEO, it gives you the chance to hide the title and the ability to edit alt tag. Furthermore, you can find their CSS file easily.
I hope this great extension supports flash-like animation in future, that’s give you the edge to compete with other rivals.
