Press the green flag. This is a random code generator, like the bar codes you see in stores. If you'd like to use the code you got for your logo, click the stop button before saving the picture. Turbo mode makes one VERY FAST, so if you're in a hurry, that's the way to go.
Thanks to @burtbees, who has a project called Logo Generator that I tried to get ideas from, but the scripts were too complicated. XD Thanks for the inspiration anyway! Also thanks to Shark Tank, from where I got the inspiration to make this!
