Well, I purchased it - I couldn't resist the B&W interface - and then I remade the ICONS and I really enjoy being able to customize the interface in Moi.CSS lots. Still - what I am interested in is PARAMETRICS & ORGANIC design - you know, symmetry - golden ratio - fibonacci - chaos theory designing - being able to use sunflower seed heads - double matrix, as well as TERRAZZO layouts - patterns. I've tried a few programs like Armadillo ArrayPlus & Parametric plugins - however, for me, they're not that intuitive, at least not as much as Moi3d. I find Moi3d commands much more sensible when it comes to aligning, arrays and pattern making. If I had my druthers it would be steering Moi3d empowering it more towards where t-Splines left off. Now that t-Splines has quit Rhino, I have no use for Rhino anymore, because I can't think how to do the organic shapes without t-Splines in Rhino (5). So now I'm pinning my hopes on Moi3d - perhaps Moi3d will compensate for the loss of t-Splines (to some extent) as it evolves, and add more PARAMETRIC tools - which - in my opinion - would make it a god-send. Cheers! I think this is the best software I've seen in 10 years~! Here are some ICONS, attached, plus the Moi.css file in TXT format - and a screenShot of my favorite GUI:

The Moi3D txt file (Moi.css in text format which I've customized) didn't upload - doesn't open - so I've pasted it below:
