Ascii Art Mandelbrot Fractal Zoom

As part of my DHTML++ demo, I wrote an ASCII Art Mandebrot Fractal zoomer. Unfortunately, the current version is waaaay to slow to calculate the frames in real-time. Apparently they did not optimize JavaScript in Internet Explorer for rendering fractals in real time. I am working on a much smarter algorithm, which only calculates the fractal once. I intend to use variable accuracy. This means I can get more detail around the area I zoom in to, so I do not need to recalculate the fractal for every frame. However, this is a bit more complex than it sounds, so don't hold your breath. In the mean time, here's an example of what it will look like.
