Totally Tectonic digital wallpaper #DecemberReward (Patreon)

This month's digital wallpapers come to you from our lesson, "How North America got its shape" by Peter J. Haproff, animation by Globizco.

This is a great lesson to remind yourself that some of the most breathtaking views of seemingly indestructible rock formations are caused by the faulting, folding and stacking of rock as if it were nothing more than a sheet of paper. 

In more ways than one, this month's wallpaper is about perspective.
