Shaffner spoke to Great Big Story about how he got involved with the show, what things were planned and what things were happy accidents, and how his designs impacted not just the show but culture in a massive way.

When you think about it, it's a lot of responsibility and we owe a lot to Shaffner and his designs. We honestly could have listened to him talk about this for hours.
