Click and drag the mouse over the image to highlight an area to zoom, or Shift+Click and drag to move the image around. The most interesting areas can be found by zooming in on sections of the set's border, which is the edge of the black area. The color scheme can be changed in the menu. When you find the perfect image, save it using the save button in the menu. Below the application are sample pictures I've taken during testing. If you zoom in really, really, really far you'll eventually see pixelation. That's due to the limits a computer has in representing very, very, very small numbers. It is possible to write code to circumvent that problem, but it would slow down the program significantly. Besides, it's kind of fun to push a computer to the edge and see what it looks like. Enjoy exploring!
