Pi needs 80 steps to show it´s face. You see here the pi-ramid from step 31 to step 80. Discovering this face was very exciting. first I saw the lips then the eyes and then the complete face. Wouw!!!
The middle part of the Pi-ramid´s steps 31-80. The face is coming out.
To show it better I paint some of the symmetric digits black. Interesting: The 8 is to be seen the first time in the middle line (step 50).
