Gravity Simulations with Particle Streams

A compilation of gravity force simulations. Animations show what happens to a stream of particles when the force of gravity changes, or the source of gravity moves. These simulations were baked using Blender’s physics system.


Flower like shapes and interesting stream knots can be seen forming in the video below.

Subreddit Relationships by Mods (The_Donald, AgainstHateSubreddits, and TheBanOut2018)

I thought it would be interesting to see how specific subreddits are related to one another by their mods.

Here is an example of a single mod to many sub relationship.

Three root subreddits where chosen: r/The_Donald, r/AgainstHateSubreddits, and r/TheBanOut2018. Below are wordclouds showing what other subreddits share the same mods as the root subreddit. The font size is the scale for how many mods from the root sub are in another sub. The larger the font, the more mods they share with the root sub. For AHS and TheBanOut2018 clouds a mod relationship less than 4 where filtered out.
