3 or so years ago I had a theme on my computer that I really liked. The background it came with was a big neon green biohazard sign on black background or the blue blackhole picture from digitalblasphemy.com . The color scheme was like darker blue/darker to lighter green. Anyone have an possible ideas? It was along time ago though... It came with a damn good bit of icons too. Any help appreciated.

Oh, the blue blackhole background from digitalblaphemy was called Singularity if this helps. Thanks

what modules were in the theme?

customize.org has a selection of older themes. maybe you have some luck there. don´t expect these older themes to run out of the box though.
