So I own exactly two lava lamps, which were bought as a sort of joke I no longer remember the origins of; one was originally for me, the other for my then-boyfriend. The problem with then-boyfriends is occasionally they turn into now-husbands, which is why I now (jointly) own two lava lamps.
As it turns out, they are the same two lava lamps that power a good chunk of the internet’s crypto. Huh. So I guess now my old lamps have gone from “tacky 70s holdover” to “tweet cybersecurity in-joke”. Which, y’know. I can totally live with.
