Tetrastar fractal script by mcld

The PHP script can be passed variables to indicate the number of iterations, the rotation of each iteration, and the size ratio of each iteration. If they aren't set then the values are randomised, as is the colour scheme.... Each of the images below is fetched with exactly the same URL (no variables, hence randomised). (Except that I use a dummy variable to force your browser to call the script again for each image.)

You can play with the variables yourself at this page.
