I build replica props out of EVA foam, several years ago I built a full proton pack using just EVA foam. I do a lot of art, spray paint paintings, Book Nook's, Dioramas, full size replicas, you name it I build it or at least try.
I have built several large props including a Star Gate for conventions to use. I have been a quest at several conventions where I talk about prop building and display my work and do Q&A's. My most favorite was when I was on stage answering questions sitting along side Brian Muir!.
