Lunapic is well worth a deeper investigation than just the first page. It is a very easy to use image manipulator. Both fun and useful.
There are many, many different effects that you can add to your image.
I have heated up the Lunapic logo, and the two lads, from one of our events, to the right, are really reflecting on their work. Old movie scratches, rotating cubes of a few images, or even let your image be struck by lightning! The end results can be exported as gifs.
