We should be able to have ant farms, not for any super cool use, just because you could. Like, imagine having to micro-manage one, so you could get empresses or something, but removing them too quickly would kill the colony. Or they could just give a certain amount of items at a certain q at times, and could be a generic garbage can cause ants will eat damn near any organic matter. Maybe they would spawn ants if you didn't take ants out for long enough, and then turn into an anthill if left untreated for even longer.

Would be funny if someone made a bunch of ant farms around a base and fucked with them.
