Cuboid hedgehogs are the cutest hedgehogs. This GIF is from a "preview of a biome's artistic development" from Planets³, the Kickstarter-funded Minecraftlike that's going pre-alpha in January.

Unsurprising given its success, Minecraft has, let's say, inspired a whole range of new games. Some, like Terraria, have been pretty good. Others, like the endless sea of shameless clones, have been terribly unimaginative. At first glance Planets³ sounds like the latter.
