This one’s a bit weird, so prepare yourself. Bobby Fingers is my favorite tiny YouTube channel. He meticulously creates incredibly detailed dioramas of problematic celebrities in infamous moments, then buries those dioramas somewhere in the world for you to find. If that sounds bad, it’s better than it sounds. If that sounds awesome - well, it’s better than it sounds. There are only 3 so far, and I’d recommend starting at the beginning, with Mel Gibson.
The Vesuvius Challenge seems pretty cool to me. Some science nerds figured out how to simulate unwrapping the Herculaneum Papyri, which were buried during the eruption of Mount Vesuvius in 79 AD, without damaging them. Now some other science nerds are trying to convince even more science nerds to help them detect the writing using computer vision so they can translate it. It’s science nerds all the way down, baby!
