Screensaver mode

Hello,

Thank you for the wonderful program, its a beautiful addition to the right desktop! I was wondering if its possible to exit bonsai.sh after hitting spacebar or q? Currently, it only seems possible after hitting ctrl-c. I ask because I like to use it as a screensaver, and as with any screensaver, your first instinct is to hit space or wiggle your mouse or what have you. Perhaps you could introduce a screensaver mode if you have the time?
