I used this image I took of a mural I saw in Puerto Rico to create this vapor wave. I did it on my iPhone using the apps Professor Michael suggested, Ultrapop and ImgPlayPro. I was very surprised at how easy it was. The only challenge I came across was having to use multiple variations of the image to create the animation. It was kind of a slap on the forehead kind of moment because that should have been pretty obvious but hindsight is 20/20.
