Submission + - GNU Savannah Site Compromised (threatpost.com)
The compromise was the result of a SQL injection attack against the savannah.gnu.org site within the last couple of days and the site is still offline now. A notice on the site says that the group has finished the process of restoring all of the data from a clean backup and bringing up access to some resources, but is still in the middle of adjusting its security settings.

We're comparing a power 8 version of the generlized Mandelbrot formula (Zn+1=Zn^k + C, with k=8) against a power-2 quaternion Julia.
In the epilogue, the author admits that there's less variety in the Mandelbulb-8 than even in the classic Mandelbrot.

The common Mandelbrot set is really a 2-dimensional slice of a 4-dimensional object identified by both the combination of the complex numbers Z0 and C in the canonical Zn+1 = Zn^2 + C. The mandelbrot set lives in the plane where Z0 = 0 + 0i, while the Julia sets live on infinitely-many-squared orthogonal planes in the remaining two dimensions, each one intersecting Mandelbrot's plane in a single point of complex coordinates C.
Visualizing this hyperspace monster was made easy by POV-Ray. It took my computer two week of computation to render 80 seconds of animated 3D slices of a the quaternion. Check out the scene source.
