Irrational Number Line Games, LLC
I ended up with an extra clear dice case from this sci fi terrain bit and have always wanted to make a gelatinous rectangular prism.
I coloured the inside and outside of the case with green Sharpie, then glued some plastic wrap strips on the outside and repeated the colouring.
I touched the outside up with some metallic green paint, then sealed it with gloss Mod Podge.
Works pretty well to seal up Lil' Lobo, too!
While I am not adverse to scenarios with rock guitarists being attacked my gelatinous masses, this is a more traditional setting, I believe.
