What makes a happy product?

A great question on linkedin by Karen Vu
One simple happy question: How do you make a 'happy' product ?

my answer: maybe it's fuzziness.. quirkiness.. asymmetry.. simplicity.?. an unexpected response to a stimuli.. fragrance.. color.. taste.. sound. temperature? lack there of?music? a clean slate? dark chocolate? vermillion? white? stars? fading light? is it R2D2? i dont know? deviant is a prerequisite.. triggers of memory.. metaphors that take you to another world. that make you fall in love. that bring inanimate objects to life.

humanity in unexpected places/things.. makes a happy product.
