LOL - It has been a long time since I made this thing. Not even sure how I did it, other than simply tossing the GIF into the background.
*Actually, I think this GIF file had to be used as the TableRT.png. I am assuming the FTP client was able to read the animated GIF in place of the PNG image, but I dont know if the client will be able to read the animated GIF in place of the background.jpg, that sits behind the TableRT.PNG. This also means that Stars would almost certainly not support this, as they use BMPs/Alpha-Masks.
I ended up using small chunks of this image as a card back also. I have never attempted this with stars. And I barely even remember creating this, FWIW.
Perhaps these are a bit better? Not actually animated, but might start looking animated after a long session. :P
