POGL's grafman is Reporting Live from San Diego - collecting ideas for the next release of Perl OpenGL.

Just prior to SIGGRAPH, grafman created an animated/dynamic photo tiler using POGL, PerlMagick and Günter Bachelier's tiling algorithms.

During breaks at SIGGRAPH, grafman has converted this into a psychodelic screen-saver, which he will post after SIGGRAPH.

You can check out a screen-cap on POGL's gallery.
