Here’s something I read in Ilium. It was pretty interesting to me. Hopefully you have as much trouble with it as I did. The difficulty was interesting. I am going to name shapes of a certain color and their orientation in relation to each other. All you have to do is picture the colored shapes against a white background. These are the shapes as far as I can remember.
One yellow circle with a green triangle in it
Easy enough?
Three red circles with blue squares in the center of each.
A little harder
Imagine three rows. Visualize four blue rectangles above three red circles above four green triangles
I find the third visualization extremely difficult. Well, I thought these shapes were interesting enough to share.
