If you look at the Innoventions wall you can find a hidden mickey.  However, the Innovations wall moves around in a circle so the hidden mickey may be out of site.  While the wall is spinning around look out for a TV set.  On the face of the TV set you will find a classic hidden mickey.

Here are some pictures of the hidden mickey on the Innoventions wall.

If you look on either the mural in the beginning of the queue inside of the building or at the mural at the exit of the ride where you look at the photos you will see a hidden mickey.  The hidden mickey lies on the planet K’tleendon Kan Cluster.  If you look at the cluster you will see an upside-down classic hidden mickey.

There are a few hidden mickeys on the mural that has the various planets on it.  This particular hidden mickey is on the planet K’lifooel’ch.  This planet has many spheres that make the planet.  If you look carefully you can find a classic hidden mickey created by the spheres of the K’lifooel’ch planet.

As you enter Buzz Lightyear you there will be a mural on the wall with various planets.  One of the planets is called Ska-densii.  You will find a profile hidden mickey created out of the continents.  The planet looks similar to the planet earth.  This mural is located once early when you enter the building and once at the exit where you view your photos.

There is a hidden mickey on Space Mountain located on the coaster itself.  Look carefully at the three speakers between the seats. 

If you notice there is one large speaker on the bottom and two small symetrical speakers above it that create a classic hidden mickey.
