What do you see?
 |  |  |  |
What do you think could make the shapes different from each other?
The radius of the circle can be changed while the circle is being drawn by changing the steps and amount of turning. These changes can create spirals or multiple circles.

Heighway's dragon fractal curves
What do you see?
 |  |  |

These fractal curves were displayed at the start of each section of the Michael Crichton novel, Jurassic Park.
