Truely awesome indeed! You have shown us some pictures of this project earlier. This has progressed much more now. Most amazing part is the modulairity, this makes it so playable. Grrr, Imrahil
Okay, I have to ask. What is that yellow substance used to make most of that? It looks a little like foamboard, but I have never seen foamboard with that kind of texture and carve-ability.
Spoiler: if you really need to ask why given the randomness, i've made a list: Xmas Easter St. Patrick's day 4th of july Helloween Thanksgiving my d6 rolled a 2.
It is definitely some kind of foam, but I have no idea what kind. I wish I knew more of the various types of foam that hobbyists use to create such beautiful works of art!
