I feel I managed to capture the shift from background to foreground Ligon had in his piece. I had intended to add more lines and gradients, but I lost track of time. I'm afraid the gradient does not progress quickly enough to show the transition from a black to a white spiral.
If I were to do it again, I'd like to animate the spiral such that it moves back and forth within the gradient. That would better display the transition I wanted.
Is this a good/useful/informative piece of content to include in the project? Have your say!
