Here are some images of Dave Porter's post apocalyptic/futuristic diorama and here in his own words is his description.
This is a post-apocalyptic/futuristic scene that I built using an amalgam of models from the Japanimation TV shows “Orguss” and “Votoms” with 25mm “Battletech” figures thrown in for good measure. The smaller robots and some soldiers are hiding in the ruins and are just about to capture the crew of the large mech. The ruins are built from electronic component packing material, parts from the spares box, and burned out electronics parts. I made this piece twenty years ago and I remember it being a lot of fun to put together.
