An excellent first attempt. Next time I would try it with a gif that is a little longer, the quick movement in the corner was distracting.I have but one question though, what editing program did you use to make this with? I have several gifs that I want to caption, but don't have sufficient software.
It was just an experiment for me so I'm glad with the result. :) It's been done with photoshop but the process is very complicated and I'm still looking for an easier way.
