One-A-Day: Qtips

Today’s example is short but sweet. It creates a design made out of a bunch of qtip-like ‘sticks’ with balls on the ends.

It is a design made out of ‘almost squares’ (four sides each at an 85 degree angle to each other). The turtle then turns right 5 degrees, and slides left 20 before continuing to the next almost-square.

Each side of the almost-square is coloured based on its iteration in the almost-square loop, and the fill colour of the balls is set to match. Also, each iteration is raised an amount relative to its iteration, creating a pleasing 3D effect.
