On the internet there is an image that explains how to draw an owl.

With the possibility of stating something similar I will give you the fish shape as a black box. I can imagine that you feel a bit disappointed. In my defense you should take a look at the definition of the fish.

You can use the fish by using the right module.

# #![allow(unused_variables)]
#fn main() {
use eschers::shape::letter;
#}

and calling the appropriate function, which is aptly named fish.

# #![allow(unused_variables)]
#fn main() {
let shapes = escher::fish();
#}

With our fishing rod in hand and our picture primitives under our belt, we are ready to scale mount Escher. We will do that be defining some tiles and stitching them together in our final image.
