"I like working fast to have a quick result, that’s why I use simple forms to start. Then I leave the creation for awhile—hours, days, weeks—and [when I come back to] work on it again [I] add accessories, details, refining lights, shadows, texture. What really [matters to me are] not details but the [overall seductive] aspect."
-Olivier Bucheron aka Zamak
