This program created by Clive Pygott is for viewing and modeling sims. User can choose the background color, background image, camera and lighting and pose sims together for their model shots. Users can create a pose library and share it with other artists as well.
Unfortunately, Clive has removed his support documentation for Simpose. :(
Simposeium enables the user to create all sorts of different effects for pictures. While it doesn't serve any useful purpose to the average person, but developers may find it useful for skinning, as you are able to see the finer details. One can also add a little style and flare to their skin images.
