The Mandelbrot Explorer website was looking quite tired and dated - it's now got a brand new theme.
That means it's now fully responsive - it will display and view correctly on small-screen devices. (Mandelbrot Explorer needs Windows to run, but the website gets many visits from all kinds of devices).
There are still a few CSS issues to iron out here and there, but hopefully the site is easier to use. Version 3.4 is nearly ready for release — watch out for a release announcement shortly.
