I would guess that the other side of the spinner has Gene's tounge on it, such that spinning it would give the illusion of the tounge appearing with the picture of the face.

I would have liked to see Ace on the other side and more of Ace on the Pinny everywhere.
The tounge on the other side was also a great idea.

I wonder if someone will do a replacement of the Gene Head and do a ACE or Paul or Peter version.
If I had my choice, an ACE head with a tounge would be cool but maybe a tattoo of a guitar on the tounge for Ace, drums for Peter, and a microphone or guitar on the tounge for Paul Stanley.

This machine will be a dream for aftermarket custom mods.

Still no talk or ideas for a KISS topper, but I was thinking a neon shaped exactly like the

KISS letters and a colour changing set of RGB Leds in it.

Bet someone adds a mini gas propane fire job to the headbox, push a button and a quick gas fire might appear. Done right it might look cool if done safely. Someone crazy will do it I am sure !
