When YouTuber MrBeast hit 20 million subscribers, it kicked off the promise to plant 20 million new trees by 2020. While seeming rather mad for a single person to attempt such a feat, the channel has begun an organized effort under the banner of ‘Team Trees‘.

The Basics of Persistence of Vision Projects
https://hackaday.com/2019/10/29/the-basics-of-persistence-of-vision-projects/
Persistence of Vision (POV) is a curious part of the human visual system. It’s the effect by which the perception of an image lingers after light has stopped entering the eye.

Josephine Peary, First Lady of the Arctic
https://hackaday.com/2019/10/29/josephine-peary-first-lady-of-the-arctic/
In the late nineteenth century, there was only one Earthly frontier left to discover: the North Pole. Many men had died or gone insane trying to reach 90°N, which, unlike the solidly continental South Pole, hides within a shifting polar sea.
