See I'd say these are unimaginative because they're all too similar. Once you've seen one you've seen them all, and they're all the same degree of gaudy. It's like the McMansion of fractals, intended only to overwhelm you with the impression that the creator has a really good rendering engine.

Maybe I'd be more impressed to see the process, but every time I watch one of those videos of someone making fractal art, it's just them tinkering with settings on some fractal rendering engine they bought online.

Of course, this all just shows my standard for good fractal art (and good art in general) is orthogonal to "using a powerful rendering engine."
