Of the countless DIY YouTube channels out there, Primitive Technology has to be one of the most impressive. Starring an unidentified Australian protagonist—known as "Prim" by some within the channel's millions of followers—the videos document our primitive hero building huts, spears, a forge, and all kinds of other tools for survival using only what he finds in the bush of Northern Queensland.

Perhaps one of the most impressive projects, for the labor, time and complexity involved, is the tiled roof hut, complete with in-floor heating and an oven. How's that for design/build?

Despite always appearing shirtless in his videos, Prim still has a t-shirt tan, backing up the channel's origin story as a free-time hobby within a dude's otherwise modern life (although he'd like to pursue it full-time). All of his videos have millions of views, presenting one kind of project each episode, with no narration or introduction—only occasional subtitles—making them remarkable pedagogical resources for those seeking to simply watch and learn.
