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:
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)
