Hi AL and good morning.

I'm glad to see that Karsten has already resolved your request with this reply : http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.143
I had no doubt!

Frankly speaking, as I already told many times, math is absolutely NOT my field of software developing,
and Project Elephant can really grows only with people like the (big) Max, Karsten, James (JFH), you and a few more people
whose name I sincerely don't remember (I'm sorry).

In fact, the nodes I have written (PatternSelectArray, ArrayShuffler, ArrayFlipper, ArrayLogger, SelectedObjExt) and some other
nodes of which I spoke in some previous posts (Boolean node for PointArray and ArrayMathTrasformations) are only ideas
that not requires math knowledge and are simply a bunch of JS code assembled using the code of other nodes,
a brief reading to Moi's Api docs (http://moi.maxsm.net/api/) and, ultimately, my intuition :)

Excluding some time off, spent playing with 3D modelling, really I don't have much free time to dedicate to Project Elephant developing.

So, happy coding to you and the other guys and best wishes for all :)

Have a nice day.
