Just a little electrocuted Derpy to perch atop my mystical orb of fate's destiny.
Made entirely from Creall Do & Dry modeling paste, the cloud is a big wad of aluminium foil covered in the same. Painted with Acrylic paint and varnish. Eyelashes are paper, painted black. A grounding wire is attached to the back of the cloud, so it looks like there's always lightning coming from it.
Fun fact! If you place a conductive metallic mass with a large surface area (like a ball of aluminium foil sculpted to look like a cloud) on top of a plasma ball, It basically acts like a capacitor and stores a considerable static charge, as well as generating a lot of heat. The discharge caused by touching such an item may cause mild electric shock, burns to the skin and, more importantly, to your precious sculpture that you just painted and now have to touch up again. Argh! Oh well, live and learn. The smell of burning flesh is proof that science is being done!
So yeah, I'm not selling this one. Firstly because I don't want to get sued for electrocuting anyone, and secondly because IT IS AWESOME AND YOU CAN'T HAVE IT! Trololololo!
