I spent many hours experimenting with Fractint, trying to get the inner and outer coloring just right, along with the zoom magnification that I could handle walking away from the computer for long enough to get something interesting. The worst was zooming somewhere that looked interesting, and coming back many hours later to find out you had nothing of value.

I spent my early teen years addicted to Fractint, before I could even really show off my creations except in person to my friends. I still look back at those days as more interesting with computers than now. Maybe I need to go back and write my own software to render fractals (or work on existing fractal software and see if I can improve it). In the mid-2000's, I was using GnoFract4D to render fractals, and the results were far more impressive. A change in GNOME or Ubuntu created an issue with the render window for me, and I ended up abandoning it.
