Move your mouse around to make a rainbow art piece! Press the space button to erase it all. (Sorry, this function is not mobile-friendly.) Press the down arrow to make the cat smaller, and the up arrow to make it bigger. (Or scroll up and down, only recommended in full screen mode.)
If you want to try something cool, hold the up arrow until the cat fills the screen, press space to erase it all (optional), and then hold the down arrow. Comment what you think of it.
