Very creative banknote pictures

I know art is an expensive thing, but this is really too much. I’ve never seen art like this and a usage of banknotes like this. It reminds me of mosaics but instead of little colored pieces of rocks the artist here is cutting banknotes into small pieces and gluing them together to form a new and creative picture. It seems really colorful and lively, but I don’t thing I would use my money in this way.
