:chuckle: About time someone did. As for tools, you know what celestial mechanics is supposed to be about? Now imagine a celestial mechanic in a coverall (made of sparkly stuff?) with logo on the back and gadget-filled tool box... with a lever for moving planets, star bit, starter cables, crescent wrench for those pesky moons, and whatever else I can find in the hardware store. I like visual puns, too, and half the fun of an image like that would be in identifying the elements. Carolly
