Trying out some old programs from QB45.org

Added "Rotating Parallel Planes".

It is a mod of a rotating square created with points at every x,y,z.  I found the square too hard to see from all the points, so  I changed it to have just three "slices" of points on the two outer points on the x axis and the mid points on the x axis.

And I gave the three slices (or panes) different colours to distinguish them.

Looks like you are a step away from a rotating cube. In some ways this might be harder, maybe a Rotating Sierpinski sponge?

The original code was a cube, but without the lines.  Rather a bunch of spaced out dots on the x, y, and z axes.  So many dots that it made it hard to see the cube.

A cube would be easy.  Just skip all of the dots instead of except the ones in the corners, then draw the lines between the corners.

The menger sponge, that would be a major jump for my abilities.

Right now, I'm kind of thinking a mod that rotates the planes via mouse position or clicks.  Baby steps ...
