First touch with Python . . . .gettin to know how to draw basic shapes
Here is my first drawing in class with coding.
my sheep robot. . .
My Aim about this class : " I would like to make imageBot and furthur step would be to make it move as short animated GIF"
Homework 2nd week Assignment to make your own moving robot.
This is my CloudBot. I coded in processing with python language.

I also made the gif version of Kaleidoscope by make 35 different images each turning 10 degree of the source image.
