The colors are random.
Its starts with a polygon, which is scaled, rotated and translated and painted over and over again.
There is lot of alpha in the colors and its very thin lines, hence the “nice effect”.
The only way to use matrices to represent translations is to use homogenus coordinates.
All in all it just made to look nice, and as an programming excercise.

What coordinate system? What do the colors mean?

Which means that the transformations are matrix multiplacations.
So the inspiration, for the code, is from the book and lectures.

Inspiration? don´t get it.
