				<description><![CDATA[It&#039;s my first attempt to render true 3D Julia Fractal. I used Quaternions to calculate fractal (like David Makin). Main formula is:
newx = x*x - y*y - z*z - w*w + julia_x;
newy = 2.0*x*y + 2.0*w*z + julia_y;
newz = 2.0*x*z + 2.0*y*w + julia_z;
neww = 2.0*x*w + 2.0*y*z + julia_w;

Julia coordinates:
julia_x = -1.47409435510635;
julia_y = -0.00043243408203125;
julia_z = 0.00043243408203125;
julia_w = 0;]]></description>
