We haven't checked with any doctors, but we’re pretty sure it’s physically impossible to feel unhappy while looking at Michelle Romo’s artwork. Each piece she designs for us is overflowing with cheerful characters and smiling objects. Her artwork is as eclectic as her upbringing. The childhood influences of her Japanese grandparents and American grandparents have led to an art form that blends various genres and styles. Her company, Crowded Teeth, was founded in 2004, and now designs everything from bedding to toys to art prints and more.
