A Futuron Spaceship I built with an emphasis on the Space station walls as a canopy. The tipped on their side approach made for some fussy design work with the left side and right side of the Spaceship being ostensibly top and bottom from a traditional approach to construction.
I had to come up with an alternative method of installing the minifigure, and the resulting interior is a bit clunky, if effective.
This is another one of my MOCs that hews to the Legoland Space ranges part selection, which I think helps make it look and feel like the original product range, even as I push against the boundaries of what can be done with the pieces.
