Sorry, in the nearest future this script can't get even close to Zbrush performance.
The main problem which stops me - the lack of instancing engine in MoI. This script makes thousands copies of the object, instead of making instances of one object. It consumes a lot of processor resources and memory and dramatically lowers performance of the script.
AFAIK, Michael have plans to implement support of instances in future versions of MoI.

Yesterday I spent couple of hours to increase script performance.
v.0.5 used 4 factories:
1 x orient (to place an object to a new point and than orient it)
3 x scale1d (for X, Y, Z rescaling)

v.0.6 uses only 2 factores
I've found that I can adjust xaxis and yaxis parameters of the target CoordinateFrame to process move/orient/X-scale/Y-scale using only one factory. :)
Unfortunatelly, zaxis parameter is read only, so I need to use second factory (scale1d) to correct Z-size.
Michael, please make it writeable in the next version.

Thank you ;) I'll buy a box of vodka! The next version of the script will generate even more twisted and scattered structures :))
