Explore and manipulate the Julia set.
I made this in AP Java in highschool. For some reason my teacher thought our free time should be spend honing our “problem solving skills” by playing Spider Solitaire, but I found it more interesting to continue programming and playing with graphics libraries.
Unfortunately I wrote it as an Applet, which is now nearly impossible to run due to security restrictions.
You can use arrows to translate the “camera” and numpad to navigate the Julia set. Colors and parameters can be randomized with the push of a button. While moving the camera, quality is low but by sitting still, the iteration count gradually increases.
