Need some visual inspiration? Check out the trippy fractals done by Dirk Monteny and Jock Cooper: Some of them look like bacteria, others look like Tokyo, and still others look like someone gave M.C. Escher a 3D modeling program.
The late Dirk Monteny's still-running website is here. The "Mechanical Fractals" done by (available here on his Fractal Recursions DVD) took five years to design and render, and consist of "frame by frame calculations of math equations strung together in a digital format to produce unearthly beauty."
