I wrote a little program to plot the Bifurcation fractal when I was learning to write Windows programs from scratch - this is an updated version of it. Unlike most renderings of this fractal, it uses an exposure function to get smooth gradients and scatters the horizontal coordinate around the window so you get both progressively improvements in image quality and can see very fine details (such as the horizontal lines of miniature versions of the entire picture).
You can zoom in by dragging a rectangle over the image with the left mouse button, and zoom out by dragging a rectangle with the right mouse button.
