OH it's that guy.

His double pendulum video was orgasmic.

Edit: Oh wait, no, I was thinking of the Drew's Campfire double pendulum video. That video was extra interesting because the creator is not a typical content producer. He just has a few videos without any views, then dropped what might be one of the best videos of all time, and then went back to his technical videos.

That one is a great video as well, both are good to watch back to back as they go well together.

Not sure why this is being downvoted, but I watched the recommended video in a single riveted sitting. Absolutely amazing.
