A month ago I posted 'Beautiful 3D Fractals by SubBlue' - http://kathykavan.com/3d-fractals-by-subblue - I mentioned that Tom Beddard was working on a WebGL 3D fractal renderer that lets you explore fractal structures in real time, well it's here. You'll need a WebGL enabled browser (best with Google Chrome or Firefox 4beta) and then head over to www.fractal.io and get playing!
