Random stripe patterns for crochet, knit scarves, afghans, more

This is cool!

Random Stripe Generator - "generate random stripe patterns for knitting sweaters, scarves, blankets, etc."

If I had time and energy and desire, I would write a program to generate Fibonacci sequence or Lucas number stripes with an option to repeat from X to Y and/or go up and down from A to B.

Fibonacci sequence examples:

• X=1 (note that 1 is minimum number of rows)
• Y=6 (# steps up from X) [which is 13 in this case]
• repeat (uses X and Y)
  • 1 1 2 3 5 8 13 1 1 2 3 5 8 13 ...
• Z=5 (# steps down from Y) [which is 1 in this case]
• up/down (uses X, Y, and Z)
  • 1 1 2 3 5 8 13 8 5 3 2 1 2 3 5 8 13 ... (photo 1)
  • 1 1 2 3 5 8 13 13 8 5 3 2 1 1 2 3 5 8 13 ... (photo 2)
• Z=6 (# steps down from Y) [which is also 1 in this case]
• up/down (uses X, Y, and Z)
  • 1 1 2 3 5 8 13 8 5 3 2 1 1 1 2 3 5 8 13 ...
  • 1 1 2 3 5 8 13 13 8 5 3 2 1 1 1 1 2 3 5 8 13 ...

• X=3
• Y=4 (# steps up from X)
• repeat (uses X and Y)
  • 3 5 8 13 21 3 5 8 13 21 ...
• Z=5 (# steps down from X)
• up/down (uses X, Y, and Z)
  • 3 5 8 13 21 13 8 5 3 2 3 5 8 13 21 ...
  • 3 5 8 13 21 21 13 8 5 3 2 3 5 8 13 21 ...
• Z=6 (# steps down from X)
• up/down (uses X, Y, and Z)
  • 3 5 8 13 21 13 8 5 3 2 1 2 3 5 8 13 21 ...
  • 3 5 8 13 21 21 13 8 5 3 2 1 1 2 3 5 8 13 21 ...
• Z=7 (# steps down from X)
• up/down (uses X, Y, and Z)
  • 3 5 8 13 21 13 8 5 3 2 1 1 1 2 3 5 8 13 21 ...
  • 3 5 8 13 21 21 13 8 5 3 2 1 1 1 1 2 3 5 8 13 21 ...
