Anna Weltman and Dan Meyer are hosting a mathematical art contest based around loop-de-loops. We worked on paper first (CMONMATTTHINK), and then went to python. This was day one of python for the class, so it was a great intro without going too crazy in depth. The rules: you must keep the following setup, move(some distance), and left(90). Other than that they could change the number of times it looped, how many instructions were in the loop, etc. Here’s a code sample:

from turtle import * multiplier = 30 speed(0) for i in range(1,100): forward(3*multiplier) left(90) forward(1*multiplier) left(90) forward(4*multiplier) left(90) forward(2*multiplier) left(90) forward(7*multiplier) left(90)

Here are some of their marvelous creations:
