Try using a bowl with a bit of burning oil.
I've only just started learning to do this sort of stuff so i'M NOT GOOD AT ANY OF THEM lol! but i know what you mean about the oil. I once was just staring at my oil burner that had a bit of oil left in it and suddenly I could've sworn the colourful stuff swirling on the surface moved into the shape of a rabbit!
eek
