The earliest known episode of "Scooby-Doo", entitled "The Fiendish Drapery Phantom" was shown in drawing rooms all across North America in 1885.
Even then, the cleverly disguised villain "Would have gotten away with it if it wasn't for those meddling kids."
Of course, back in those bygone days of innocence, writers could get away with unbelievable plot lines.

Blancmange Function

The Blancmange function, also called the Takagi fractal curve (Peitgen and Saupe 1988), is a pathological continuous function which is nowhere differentiable. The iterations towards the continuous function are batrachions resembling the Hofstadter-Conway $10,000 sequence. The first six iterations are illustrated below. The dth iteration contains N+1 points, where N=2d, and can be obtained by setting b(0)=b(N)=0, letting

b(m+2(n-1))=2n+1/2[b(m)+b(m+2n)],

and looping over n=d to 1 by steps of -1 and m=0 to N-1 by steps of 2n.
