I've just been searching for widgets to add to one's blog, under the term "fractal". Seems there aren't any. I was thinking, for example, of something which lets the blog viewer input coordinates for the Mandelbrot set, by numbers or by pointing the mouse; or allows one to try out iterations of a choice of L-systems, or to play with holons of an IFS. These would be really cool to have. Anyone interested in programming such?
