All technology used by art has some sort of science behind it today. However, there is even art in the formation of science and the development of hypothesis. There is just some things you can't use a recipe to generate. Science is all about repeatable processes. Art is not a repeatable process. Well, that which differentiates art from science, is non-repeatable processes to make it a work of art.
mostly science... since technology is the application of scientific knowledge for practical purposes...
