Dear Steve and Brian,
First of all, I want to thank you for all your help!
I would like just to keep the Law and Order episode a little longer.
You can see that the sphere in the top right is indeed a hemisphere or some “3D” object.
I was thinking if the yellow dot/ circle was made with a simple disc (that is the same Y,X,Z position of the rectangle shape) and with some keyframes was animated to expand is size?
And the same with the 3 little circles that appear, with a display (?) tag?
Thanks again!
