Wavelength 477nm, also known as Eric Andresen is a budding sports photographer, more used to doing travel photography, but was looped into Roller Derby in December 2009. He's now been christened as the league photographer for the Zürich City Rollergirlz.

Zürich City Rollergirlz is the first roller derby league in Switzerland. We play women’s flat track roller derby by current WFTDA rules. It is our goal to bring a sport we love to a country we call home. It’s been a fun and interesting journey to spread the love of a brand new sport to a place that’s never heard of it. Not only do we have all of the normal challenges of starting a league but we also have to create the interest, build the fan base, and find the surfaces to skate on. Most of our conversations start with the most basic of questions - what is roller derby?
