A variety of fractals can be explored in the space of quaternions. For example, fixing j=k=0 gives the complex plane, allowing the Mandelbrot set.

I never understood the concept of a quaternion, though I've used its parameter quite often in Mandelbulb 3D. So I know what you're talking about, and I've used it before several times... but I don't understand its math.

Their definition is simple; their use is above my pay grade. i squared = j squared = k squared.
This may intrigue you:
