Dos and Don’ts of Scrambled Rubik’s Cube Costumes.

It’s Halloween and from time to time you will see some Rubik’s Cube costumes. As one does.  Some of them are store-bought.  The great ones are do-it-yourself jobs. Who wouldn’t want to take on the task of making a cardboard costume?  Of these homemade costumes, the scrambled cubes are the most interesting to look at.  And of the scrambled cube costumes, the ones that could theoretically be solved are the best.

Drawing a Spherical Panorama

A spherical panorama is one that captures, not just 360° around, but all the way up and down too. It captures every direction. I want to show you how you can hand draw (or sketch, paint, etc.) these panoramas.
