Assorted Links April 2026

I figured I'd combine a bunch of links I'd recommended to friends on discord in the past:

3d printing a film camera The results are pretty stunning and he's a great video editor. Lot of cool details about how film cameras work.

4 axis 3d printer with non planar slicer It turns out a big part of 3d printing arbitrary shapes without lots of supports that need removing afterwards is the algorithm for converting the shape into individual flat "slices" that 1. won't collapse and 2. are physically reachable by the printer nozzle.

Lego Island: Great documentary with real interviews from many of the devs, with a lot of info about the very early days of 3d games on pc.

The sounds of the ice shelves breaking are amazing.

When is easter? I like when things turn out to have very complicated histories. This dives into the calculation on how the date for Easter is determined each year.

Backyard Ultramarathons Keep running 4.167 miles every hour until, everybody else gives up (potentially for 24+ hours). (wikipedia)

The Crafsman makes hundreds of plastic figures Guy with a soothing folksy voice uses injection molding to mass produce a little figurine. The paired video of another youtuber CNC'ing the mold is also fascinating.
