Mouth of Flower - Octavio Ocampo This is good art because it is an optical illusion. It could either be just some flowers with a butterfly, or you can also see a woman's face. It is very creative in a subtle way.
Dotted Heart by Francesco Bagnato, via Behance. I am planning a color tattoo for my siblings, each having the color that represents them. It would be cool to do this and fill in the empty space with the colors!
