Press spacebar or click the pause button to turn settings on/off. Press the "s" key to toggle if the unicorn is showing or not. Press the "c" key to clear.
Thanks, @adamhe, for making the original! I added a thumbnail, changed the title and added the ability to toggle if the unicorn is showing or not, the speed of the pen (unicorn), clear and the preciseness of the rainbow's changing colors. Note: There is one bug: sometimes the ability to toggle if the unicorn is showing or not doesn't work.
