The Smurf Projector is a device Gargamel created in the 1980s cartoon show episode "The Magical Meanie". It resembles a reel-to-reel film projector, yet it is turned by a crank that powers the projector. It projects whatever image it finds of the Smurfs onto a wall through a ray of light.
In the episode, Gargamel uses this device to spy on the Smurfs when he happens across Brainy and Clumsy carrying Genie Meanie into the Smurf Village, overhearing that if they say the magic words, they can have three wishes granted unto them. Gargamel cranked the projector even faster to find out more, but the projector exploded, leaving Gargamel with the desire to get his hands on that genie so he could make three wishes that he could use against the Smurfs.
