Von Neumann's Elephant

Post by jgharston »

On a Wiki walk earlier I came across Von Neumann's Elephant. This comes from a comment from Von Neumann that "with any four free variables I can model an elephant". In 2010 such a model was discovered:

Code: Select all

      REM > Elephant
      REM Von Neumann's Elephant
      :
      FOR t=0 TO 2*PI STEP PI/1000
        PLOT 640+4*FNx(t),512+4*FNy(t)
      NEXT
      END
      :
      DEFFNx(t)=-60*COS(t)+30*SIN(t)-8*SIN(2*t)+10*SIN(3*t)
      DEFFNy(t)= 50*SIN(t)+18*SIN(2*t)-12*COS(3*t)+14*COS(5*t)

On a sample of one, not everybody will guess that it is supposed to be an elephant without being told first!

Methinks it is like a weasel.
