One of the bestest Mego playsets EVER!:
Well.... okay; there's more to it than just that. It's a geomorphic dungeon tile, that you can hook together and make dungeons!:
Or, classic Dr Who sets; depending on how you paint them. I was thinking of a stone pattern on one side, a high-tech corridor on the other. (Perfect for Mego 8" scale games of Spacehulk.)
"Wait! I hear something! Huzzah!"
"It's a 30' by 30' room.... with an orc and a treasure chest! Quick! Kill the orc!!!! Take the gold!!!!!"
Originally I was gonna make this out of cardboard; but reinforcing it enough to be played with resulted in parts that took up a LOT of room. This one collapses for easy storage:
One of the local hardware stores had a sale on scrap wood. When I got there I found this stuff: it's really solid, heavy, and saw resistant. (While cutting it the circular saw was sparking.) It still needs a few tweaks, but it works and can replicate all the neccessary D&D dungeon fictures; like stairs, dead ends, doors.... eventually pits. The holes in the middle are for accessories, like torch holders or support beams.
