If I end up doing a video for mine I would like to may be try melting different materials. May be both butter and chocolate.
The heat lamp might be the best option because it would give me more time to possibly take photographs and document the process. I really like the creepy effect that the blow drier has on the face but I think that the heat lamp could be better propped and left.
It looks like distance from the heat source will play a factor as well. This artist put the heat source very very close to the bunny and got a rapid effect. If I want a slower melting period I may need to have a farther away heat source. If my sculpture is solid and not hallow though it may take a close up heat source.
May be I could do multiple cows melted one with heat for exercise and one with water for diet.
