" it's one of the few places on the web where teenage boys can legally view free nudie pix."
For real people the web is full of open and free images available to be seen by anyone, but if you turn to 3d rendered images the number of sites is not big and Renderosity is one of them.
With rendered images the size is only function of the dial setting and is only limited when the mesh begins to break creating black rendered polygons.

Stupidity also evolves!
