The illusion of shape changing
I read that you cannot tween between two different shapes with Flash, and didn't think about it until I accidentally noticed an "apparent" shape change in something I was working on.
When I had an elliptical illumination moving across the page, it appeared to narrow to a line, then widen back to an ellipse.
What had happened was that I had (for some reason) inverted the image from one side to the other. As it moved, it inverted, appearing to have changed shapes!
This made me think. I tried it without inversion, then mirrored it. It appeared to shrink from an ellipse to a circle then back to an ellipse as it crossed the page.
My sample here shows both effects, beginning with simple page crossing, then the narrowning/widening and finally changing from a large ellipse to a small ball and back. Hope some of you will find this little trick entertaining or even useful!
Wish I could claim brilliance for this, but it was pure accident.
