That Rhino newsletter from Bob McNeel is always fascinating, and usually includes one or two new tools free for the testing (this is how Rhino beta tests things).
If only certain other software companies worked that way!
By the way, the future of scripting might be something described here, linked in that same newsletter (I've also been testing this):

They call it "Explicit History", but you should really think of it as scripting with a graphical interface based on the concept of nodes. Blender and Nvidia's shader designer have incorporated similar interfaces, as have certain FEA tools and various performance/video packages like Max/Jitter, PD, and VVVV.
