Maskit Verdigris Horns

A Maskit-slice Kleinian limit set with generators a(z) = mu + 1/z and b(z) = z + 2, at the 6/13 cusp mu = 0.9667959080258433 + 1.6804908224252035i. The cusp was found by building the Farey word through Stern-Brocot descent and taking the exact root of its trace polynomial in mu. The limit set is confined to the strip 0 <= Im z <= Im mu, so the two straight horizons are the group's own geometry. Hue is keyed to word depth over 452 million limit points.
