Port Holes and Planetoids

This is a picture of some port holes and some planetoids. The multi-coloured  circles are the  port holes. They take you to whole diferent worlds (the '100 acre woods' doesn't sound like a different world, but where have we found it on this Earth?).
In the picture I have port holes to Oz, the 100 acre woods, and the receiving end of Earth. The planetoids are the houses, trees, and fences. I imagine this is much like what happened too Dorothy in The Wizard of Oz.
I'll post again soon.
