Guys, many thanks for the ideas so far. Shatinator, you and me thinking the same way. Everything u wrote down is the same what I had in my mind. I want to make a decoration like inside of a starship. To be honest I don't really want to buy things, I want to do it by myself. Me and my sister are like to do creative stuff (I'm a fashion designer so I was thiking about to sew the uniforms, my sis is quite good at make up so we can probably do it to be similar like in the series.) I need some ideas about the spaceship or some infos about the creatures. Do you know any sites where I can find more photoes or funny things?
