Named thusly 'cuz it kind of looks like a water drop at the top level. Also quaternions.
This is a GPU program that draws the Mandelbrot set, using quaternions instead of complex numbers. (Quaternion fractals aren't a new idea, except to me.)
You probably want a reasonably good GPU.
Something approximately equivalent to the Julia Set available by editing main in fragment.glsl.
It's somewhat more difficult to find interesting space in it; an iteration depth of 200 is recommended.
The fractal viewer bit is forked from remexre/mandelbrot-rust-gl.
left-drag: pan x,y
right-drag: pan z,w
scroll: zoom (x,y)
r: reload shader
o/p: change iteration depth limit by 1
lbracket/rbracket: change iteration depth limit by 10
space: reset zoom
period: print out draw parameters
Collect all n.

- Theaters
- Spooky ghosts
- Creepy masks
Here's some other picture.
In general, the fractal is less regular than Mandelbrot, more wild & surprising. Unlike Mandelbrot, there are edges where recurrence ceases. Regularly recurring features are rare, but have been found.
