I've created a number of fractals specifically to convey an emotion, starting with that emotion in mind and not stopping until I've achieved what I wanted.

Emergence was about trying to escape from depression. The "cave" from which the viewer looks out is an obvious metaphor - the moon is the distant, almost unachievable goal of happiness. It's setting for a reason, always out of reach.

"Wedding," an early fractal which I haven't posted here yet, was created from the start to express the indescribable joy I felt nine years ago when first seeing my wife in her wedding dress. The colors and the free-flowing fractal are supposed to be joyous, though I don't know if anyone else sees that in the image but me. But it's a personal thing anyway, so that doesn't really matter.
