illustrator is a app where you can use almost any image and turn it into a decal or a keychain by transferring the image you want to use to illustrator and make a circle around it then transfer it on your USB then go to a laser cutter and put the finished image in and it will cut it out of a plastic sheet and for a decal you need a 3,6,16 color image then you take it apart and have each color separated from each other
