I can't draw a straight line for the life of me, so I think the Contrained Ball would be a great investment for me and my future children. I honestly feel that a steady hand is a gift, and if you're not born with it, then there's bound to be an invention that will help -- and now there is.
Designed by Giha Woo, the Contrained Ball features a rubber gasket that when fitted to a writing utensil, it helps maintain a straight line.
