Challenge # 3

Can you make your turtle walk down a path of your creation?

Using the rules:

to check-color
  if (pc-at dx dy) = red [rt 180]
  if (pc-at dx dy) = green [lt 90]
  if (pc-at dx dy) = blue [rt 90]
end

try building a StarLogo version of the path you drew.

Hint: you can use the paint tools to draw colors on the StarLogo Graphics window.
