I've come to the experts to see what's possible .... HELP!

Hi,

I have just bought a house with the perfect location for a forced perspective diorama, or at least that's what I see in my mind.

There is a window that has to filled in which is about 2 m x 1m by 20cm deep, and I was wondering if a forced perspective diorama couild be built inside the space?

My worry is that it's to shallow to get any real depth to it, failing that if anyone has any ideas of some sort of 3D trompe loi (can't spell that) then I'm all ears.

I love the idea of putting tint fibre optics or LEDs in it, happy to model landscape, use mural back drops, you name it.

Id like it to have some sort of science fiction or space theme, even cartoon might be fun like the busy opening scene from Futurama?

Basically I'm open to any suggestions you good folk might have.  Even if it's don't be mad, just fill it in with plaster board and hang a picture on it.

Thanks for your time, I look foprward to any thoughts.
