16. The Sierpinski gasket
• Your turn to recreate Sierpinski gasket
• And this is what is would look like if you
went one stage further:

17. What is a fractal????
• Often self similar
• However much you zoom in you still see a
pattern
• Often generated by a simple rule

18. What’s Special about the
Sierpinski Gasket?

19. Do other fractals have interesting
properties?
The Koch Snowflake
