CAD Demo - Curta Calculator

The Curta is a small, hand-cranked mechanical calculator introduced in 1948. It has an extremely compact design, a small cylinder that fits in the palm of the hand. It can be used to perform addition, subtraction, multiplication, division, and, with more difficulty, square roots and other operations. (c.f. Wikipedia)
