Re: [Haskell-cafe] (mostly OT) Strange patterns of commas

Now see if you can tell us why this pattern is similar: [ replicate n '-' | n <- [140..171] ] Hint: Look at the closed form as n gets big: http://en.wikipedia.org/wiki/Fibonacci_number#Closed_form_expression After that, you can tell us why it's a parabola. Matthias Kilian wrote:

Fibonacci numbers are always surprising.

Try this on a terminal that's 159 characters wide (using a properly sized xterm(1) may be a good idea):

let f = 1 : 1 : zipWith (+) f (tail f) in take 780 f
