  • Funny. All I could see were elipses...

    

  • Check out the video "The man who draws Pi" Jason Padgett under visualising equations!

  • Fascinating...  Especially the vertical/horiztonal piece at the end.

    The chap's spine around 5.50 looked well on the way to being a semi-circle!

  • Interesting for teachers!!! Thx

  • Pretty cool, interesting.
