Hi Chimera folks!

I love, love, love the new scene-based animation! I know that it is still under development, but it is fantastic! And the "Animation" utility panel is easy to use and understand. I love the "Rock" and "Roll" "Actions" available in the Animation panel. That goes a long way to making movie-making a point-and-click affair!

I would like to suggest or propose one more "Action" in addition to "Rock" and "Roll". It is "nutate" or "lemniscate". It is basically a "rock" in both the X and Y planes at the same time. I think that it can be coded relatively simply with a cosine function about the X axis concomitant to the sine function about the Y axis that is driving the current "Rock". You can see an example of what I'm talking about here:

Also, if I could, I would also suggest or propose that the "Rock" and "Nutate/Lemniscate" have a single parameter to control the "width" of the rock or nutation/lemniscation — maybe choices of 15, 30, 45, and 60 degrees or a free-form entry.

Thanks for everything you do!

Best wishes,
Darrell
