Digging around in the included examples with C2, I came across the lighting.capx file that (apparently) was created by @Ashley. (LOVING the effect, too! I'm gonna use it somehow.)
The effects and settings for the image sprite seem straight forward enough. But when I examine the animations part, I'm not quite sure if that's truly an imported image or what... Ultimately, what I'm seeking is how to initially START the object. Is it just a dot that's manipulated further? An imported image? What?
