Currently, the sign images are all static because I wanted the hassle free solution of them fitting onto all backgrounds without the matting issues you would get with animated solutions which would have resulted me in saving them in .gifs.
Saying that. I haven't got a problem posting some animated solutions across the white/light to dark/black colour spectrum so it accommodates the masses rather than the minority.
I've since released the smiley sign pack in .png format and the screenshot has been posted
(below) and in the first post of this thread.
