Wow! The demo video[1] is really impressive. How are those effects created, I wonder? Do the fractals get their own depth maps? How do you arrive at algorithms that look so darn beautiful, especially those metal and plastic shaders? Is there prior art for this?

I paid the $4 and got it. Slick & entertaining. Not as hard-core math-ish as I'd like, but fun to zoom around in. There's in-app "pro upgrade", which I find a bit irritating if that's where the greater numeric control & deeper resolution resides.

It's pretty awesome, real time fractals on your iPad, a lot to explore. Looks really great. Having parameters and textures animate while you're zooming on an iPad in real time on a fractal is impressive.

I suppose it has 2D fractals only, my Haswell CPU struggles with 3D fractals already - I wish I had a experience as smooth as in fractal lab.

I've played with it. Quite nice.
