Let's make some power discs.

Ghost Rider Bike and Ghost Rider Bike

Ghost Rider's Bike

Jakku Sky

Takodana Sky

Starkiller Base Sky

Star Wars Stars Sky

I'll make some skies for the prequels next.

Tanks Mickey&Maleficent: Awesome job.
The second Ghost Rider Bike should be Ghost Rider Riffle/Gun. My mistake.

Oh, why couldn't those Force Awakens discs be real...

Ghost Rider's Gun

Coruscant Sky

Geonosis Sky

Mustafar Sky

Naboo Sky

Cloud City Sky

Imaginationland Sky

I don't know if a Riley's mindscape skydome can be specifically identified as belonging to Imagination Land.
From what I gather, all parts of her mind that were open to the sky shared the same skydome.

^I guess I didn't think about that when I was making it.

Here's a Riley's Mindscape Sky that includes all of Riley's mind, this time with Riley instead of Joy.

I wonder how that work if we ever got a real disc?

In the movie, the mindscape cycled between night and day depending on whether Riley was awake or not.
So you might need two discs, one for each.

The one pictured above looks like a night disc.

Dagobah Sky
