Actually, I can think of one of my fractals that tries to scale back 
numbers that get too big.

https://www.shadertoy.com/view/XtscDl

When a complex number breaches an escape time barrier, my code simply 
scales it back, say z = z * .242, and tries the fractal again. It has 
the effect of exploding the fractal out beyond its original boundaries...
