Triskele Sphere and Cube
I came across a triskele sphere at this website,
http://hattifant.com/triskele-paper-globes/. I was intrigued by the sphere and I tweaked their design to make my sphere.

I then decided to modify the height of the arc by decreasing its size. In doing so, I discovered that I had to increase the width of the band to accommodate the difference. These modifications of the original triskele design resulted in a cube.
