i think the best option (though i have no idea how hard it is to do), is to pic 5 images from each subject...

5 cars
5 characters
5 humans
5 monters
a selection of images that link to other simply 3d web sites etc..
+ add a nice selection of wireframe for mshoward82


you could also have a gallery that is also devided into sections (cars/humans etc...) that the title images could link to.

one thing i like about cgtalk is that every time you enter it theres always new images at the top...this is kinda why i think its a cool idea
