Blink and you'll miss it. Steps: Draw whatever. Make background certain color. Make panel half second long. Duplicate panel. Duplicate layer of whatever you drew. Make sure to have the background on a different later than whatever you drew. Make the duplicate of whatever you drew all black. Make the background birhgt red. (Feel free to test with other colors I only did red). Make it go as fast as it can go. Duplicate first panel and move it to be the last panel and make it half a second long Whatever you do: DONT BLINK LOL
