Ok you are right about the hurting of the eyes, I will agree. But as purple said if you don't stare at it it shouldn't be too much of a bother.
I didn't intend to make it into a gif or a signature, I was testing to see how precise I could get with editing frames in and out. Its a sample of what's to come in my upcoming bout cheetah trailer (the trailer will not hurt your eyes, I promise).
