Algodoo

Use w, a, s, d to change inputs.

A very simplified replication of a mechanical multiplication based on the intercept theorem.
(Such mechanisms were used earlier inside mechanical targeting computers of warships)

Functionality: Keep an eye on the sides of the 2 triangles which are formed by the lasers!
- The theorem of intercepting lines tells us that blue/green equals red/yellow
- Yellow has a constant length of 4 (imagine it overlaps with green if b < 0)
- Therefor blue(output) = red(input a) * green(input b) / yellow(4)
