I joined the
1st Mandelbulb Teaser Contest - so here's the best I could make from the given formulas

It's a bit close to all those classic Menger fractals but I coudn't find any trees in there ...

So I put in some featuritis - Depth of Field, Reflections, Positional Lights, a Background Image to be reflected in the foreground (note to my self: learn how to map an image as intended!)
The rickety appearance of course only comes from the instabilities of JCube3

1: JCube3 - 2: ABoxVaryScale2 - one iteration for both.
Enjoy
& Good Luck!
You're complicating my voting intentions
Thank you!
