Love and kisses. - Zaphod

You may or may not need to be something of a science buff or outright geek to appreciate this Java applet. Here you get the opportunity to play Flying Spaghetti Monster and create a mini solar system. You can have a single star (sun) or two and have as many planets as you like orbiting around them. Warning, don't become particularly attached to any single world as quite often you'll find that some are bound to smash together and obliterate all the denizens worshiping you.
