I made some animations of crystallographic defect formations using equilateral spheres. Point defects, lattice regions, and other interesting patterns can be seen forming in the video below. This was created using Blender’s rigid body physics system.
Below is an animation of a laser bouncing around a triangle with open vertexes. A link to the Euler problem can be found at projecteuler.net/problem=202. This is just a visualization of the problem. This post does not contain an answer, or any algorithms.
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.
