I really wanted to try a GIF out, but I didn't know what program to use. I google searched it, and I found a website that converts images to GIFs. I tried it out although I don't have any really great pictures for a GIF, I found a couple of pictures which I could use to test it out. Ideally, though, you really need images which are captured quickly and in succession... basically, think of how a animated movie is made. Animation is a series of images in which the subject moves only a slight bit in each image.
Still, I think mine turned out kind of cool. :) You can try making your own GIF images here!
