"Singularity" was my first attempt at rendering a black hole. I created it using Lightwave 6 in 2001 as a static wallpaper but also created a looping version for my own amusement. It wasn't possible to use animated wallpaper at the time.
Animated wallpaper was finally possible with Windows Vista in 2007 and I released this to my Members in 1080p. They weren't are popular as my static renders (resource hungry to display plus they took a lot longer for me to create and render) so I didn't do very many.
