So, while I was making my signature image, I happened to come across a mention of an image format called APNG (Animated PNG). I, of course, was curious, so I downloaded a program which converted animated GIFs into APNG, and the result was actually a smaller file, which I thought was interesting, so I think I'm going to keep using it.
Question: Can you see my signature below, animated? If not, can you see a single static frame? See poll.
