I still remember when I was high school kid, our math teacher (Mr. Volansky) brought into class book with anaglyphic glasses and you could see all the trigonometry we were taught in three dimensions. On that day, I thought that's the coolest thing I have ever seen.
We already have three dimensional movies. For some reason 3D TVs are no longer selling that much, so why not to buy some cheap anaglyphic glasses, write some python code and get lost in wonderland? [Why don't we have passive glasses computer monitors is beyond my understanding. 3D games would be so much blast. And we don't need any heavy VR/AR headset. With passive glasses monitors we would have even colors.]
Enjoy the images (Merry Belated Christmas):
If you already have the glasses, you might enjoy Grand Teton National Park, Wyoming as well.
