I meant to share this a lot earlier, but I came across this again. This is more on the artsy side, but there is this video of an artist pouring aluminum in anthills. Not encouraging to pour hot metal and massacre all the ants, but it is quite interesting to see in the sense of casting the negative space. It reveals a lot of the architecture and interior the ants naturally build which can be difficult to see from the outside. By sculpture, it's really beautiful, but I'm not too sure the moral behind all this.
(But please, don't pour hot metal on ants.)
