Press "Calculate3D" to see what happens. It is a customized bulbox; bulb formula
is Benesi3Pow2, no longer the standard pow2 bulb like in the normal bulbox.

The best way to explore this wonderful fractal is to navigate through it in the 3d navi.

You can also choose the julia seed with the point and click feature. If the julia fractal
looks like a closed cube, without anything interesting outside, change ABox scale to -2  to  2 (or anything you like)

You can choose any other formula as the bulb; simply change the fo3 tab, but DO! NOT!
CHANGE! the other tabs, and DO! NOT! CHANGE! the tab order.

If you do so, remember to set in the first CondItCountR the "formula" line as the BULB formula "fo" number (now 3)
in the second CondItCountR the "formula" line as the BOX formula "fo" number (now 4)

Disadvantages.
Too bad you can't fully control the hybrids of this formula (afaik). If you know any tecnique to do so,
share it with me please!

Enjoy! Luca
