Our team thought deeply about what makes items valuable. We considered size, weight, and color. We thought about how medals in the Olympics are considered valuable, even though they’re not pure metals. We thought about how trophies for prestigious entertainment awards like Oscars and Emmys aren’t only metallic, but heavy. And we thought about the action of redeeming tokens, and, as a gesture, we liked the symbolic opportunities with tokens. The decision to have eye surgery, even LASIK, is a big decision, and we wanted to convey that the decision to bestow the gift of vision was a decision that wasn’t taken lightly either.
