So a while back, a guy on DeviantArt by the name of faustdavenport created light-up perk machine replicas. They were stunning in quality with only one downside, they were one of a kind. Below is the replica of PHD, at least one of these was created for every perk in the game.
The scale of these machines is roughly about 12" tall, I do think it would be awesome to see a recreation. Sound for the perk jingle could be added, I believe it would certainly be an attractive product for any zombies fan.
