I'm going to make some still backgrounds later! Yes, I know that the Calming Waves looks derpy :P Backgrounds: Rainbow Mosaic Calming Waves
You can use the backgrounds freely, as long as you give credit. I strongly suggest putting a bit of a ghost effect if you plan on putting text or a picture in front of the Rainbow Mosaic. Same goes for the Calming Waves, if you're using the color blue.
