Aug 12th: I really like this guide to 3D pixel-projections for games - true isometric is almost always never used, but there are a quite a few useful variants to mix and match.

Jul 5th: An aseprite plugin for making easy isometric sprites? It looks amazing

Jul 5th: Scientific American did a podcast episode about Cleo, the Math StackExchange user who posted incredible answers with zero explanation and then disappeared in 2015. I would love to know who they were and why. Terence Tao confirmed that he was not Cleo. Some people thought it was Hawking, or Ramanujan reborn. Just excellent work.

Mar 25th: Lego have just released their own Minifig builder, including custom piece printing (although only on the body). This has been a long time coming and is pretty disruptive to all the businesses who have been doing this for a while.

Mar 25th: I had been wondering for a while about what was special about the dead coral fan in Minecraft that allowed it to be used for TNT duping. The answer is enlightening:

The coral is unique in that it behaves like a block that breaks when slime it's attached to is pushed (like buttons, torches, and so on) playing the breaking animation and sending updates like any broken block, but does not actually break - continues to be affixed to the slime, pushed by it so it can pretend to break in the next cycle.
