paper 100 repeat x 0 20 { repeat y 0 50 { pen (x+4*y/3) line (x*5) 0 (y+5*x/2) 100 } } // I liked the look of pages in a book. // however, there weren't a lot of them // in the original picture, so I scaled // the line to always fit inside the DBN // window. I also increased the number // of iterations of the outside loop. // Looking at it now, I really get a // sense of pages. I also think the // curves that result near the bottom // of the screen are very interesting.
