The zip file contains one file called element90.2.ufm and it contains two fractal formulae. The Mandelbrot and Julia versions of Almost Cubic. The calculations are implemented using the component parts of the complex numbers, there is a deviation from the correct calculation in the imaginary part hence the name almost cubic.
The Mandelbrot form of the formula produced images such as
Squid 2 [link]
Spiral and Brass Shard [link]
