Abstract

A slide animation projector for the yard comprises a solenoid that forces a translating rod to reciprocate in a spiked motion. An elongated slot in the translating rod seats a slide cartridge having at least two stationary, adjacent images. The slide reciprocates in repeated succession, wherein the adjacent images give an impression of movement.
