These are a few random animations that are kind of mesmerizing if you start to focus on them. The first four are from a physics student who posts them to his tumblr account here, and the last four are from the tumblr page here. You can see the physics influence in these animations, but they are simply fun to look at without reference to origin.
These kinds of animations are like the lava lamps of the modern age. Instead of sitting in the dark with your black light on looking at flourescent geometric posters on the wall as you do your thing, now you can sit in the dark with your monitor on looking at the geometric animations on your computer. Who says society isn't advancing!
