Exactly. Might be something for you folks who are taking up the Sacred Geometry.

As barefootwisdom mentioned, Timaeus includes several references to shapes and motions, including 33b, which has this line, discussing the Demiurge giving a spherical shape to the world:

This of all shapes is the most complete and most like itself, which he [the Demiurge] gave to it because he believed likeness is incalculably more excellent than unlikeness.

A bit of a digression, but that last bit ties back into a previous theme we've seen elsewhere.

Later on, discussing motion, in 89a:

Now the best of the motions is one that occurs within oneself and is caused by oneself. This is the motion that bears the greatest kinship to understanding and to the motion of the universe.

Using the Zeyl translation, FWIW.
