No, there's no picture for this. I am not going to make a gif with 256 frames. That's right, this thing changes through 256 colours, that's a lot of colours. It uses additive blending, so it's best in dark places. You can use it to liven up a floor, completely change a wall, or put it in a shaped hole as a rainbow fill for it. It's pretty simple to use, just a big square that changes colour, nothing too fancy. Have fun.
