Red planar trajectory traced by a red point on green table can be transferred to other place thanks to a system of two prismatic joints. The yellow table and blue slider move perpendicularly to each other. The yellow table planarly translates. Each point on it reproduces the red trajectory (violet curve) thus the multiplying is possible.
A stationary point traces on the yellow table a curve that is the red trajectory flipped two times around longitudinal and traversal axes of the mechanism (or turned 180 deg. in its plane).
