I did a plassma ball from a tutorial about a month ago . I never animated it. To animate it all you would really have to do is move the layer mask for the ball, or use a lensflare effect and move it frame by frame.
I dont post my work on this forum anymore but if you PM me I can give you a link to my deviantart account where you can see it. Not sure if its what you are looking for , but if it helps you great
