I find things like this fascinating. It's always interesting to see what comes out when people sit down with their collection and just see what happens when different parts go together. I'm constantly surprised by the variety that can be created with Lego. A great example are the chairs, which act as intake type things, on the red spaceship. I like the contrast between the solid, black building and the white mummies coming out of it. The twisting, almost corckscrew effect, on the prongs on the Technic ship are very interesting too.
