If you type in "pikachu curve" or other famous fictional characters on wolfram alpha it generates a function to trace out the curve that resembles the character. See http://www.wolframalpha.com/input/?i=pikachu+curve .

Does anyone know how these curves are generated? It seems that this has been done for several characters so I doubt that they worked out the details by hand.

  • I understand how to see that the curve is indeed what it says it is, I'm curious how such a curve could be generated given a trace of an image. More specifically how do they do it on wolfram alpha. I really doubt that they recognize what each part of the function does and piece it together themselves. Some of these curves are much more extensive that the Batman curve. – B_Scheiner Dec 09 '13 at 18:34

Visit Wolfram's blog. It has many nice applications of Mathematica.
