From the README

Website: bristorbrot.org: the project home, with the algebra explained and a gallery.

Explore quadratic and cubic fractals in Bristorian algebra, and compare them with quaternion fractals. Bristorian numbers, called imordials, have ranked imaginary units. Their multiplication depends on both operand order and brackets: (zz)z and z(zz) can give different answers.

*b_brot Julia set, z² + c, at C = (−0.7, −0.35, 0.05, 0), Julia β section at β = 27° (the window rolls from j toward k; β = 0 is the B2 jbrot), camera distance 4.2.
