Discriminant Locus of Dessin D'enfants

Here is a sample pictures of the discriminant locus of dessin d'enfants of one parameter triginonal curve family {C:=(y-x^n-a)(y-2x-1)(y+x-1)| a \in P^1} with n being 2,3,4,5,6,7. They are very cool pictures. For more information about these pictures, you can look at the following paper: [Dessin D'enfants of Trigonal Curves]
