My primary 3D application is called "Moment of Inspiration". It can be found at MOI3D.com.
I have long searched for a program that was simple enough for me to use; yet, powerful enough to do something useful. I needed something that was a cross between a traditional CAD program and an organic 3D application. I found what I was looking for in MOI 3D.
I think you will be pleasantly surprised at how easy it is to form the counter-rotating star objects.
Now, between 1969 and the early 1980's I was in the business of creating well-scripted professional videos with slick sound tracks. It would be hard to prove that to a person that sees one of my current video tutorials.
I could try to pass it off as a deliberate "Stream of Consciousness" technique. But, I'm not sure that would fly. It's closer to "Stream of Unconsciousness"!!!
But, I hope that the videos are useful even with my struggling to find the right words! At least it's BOUND to be more entertaining!
What can I say? I'm old. LOL!!
For better or worse, here's how I did it using Moment of Inspiration.
Pretty slick, isn't it?
