Chasing Limits. The New CLA.

«Chasing Limits», everything revolved around the new electric CLA. Or rather, the new CLA revolved around the four teams led by Simon Ehammer, Sarah Atcho, Agnes Fischer and Jannis Reichmuth. Their goal: to maintain the pace of the CLA pacemaker for as long as possible as it raced through the steep banked curve of the Offene Rennbahn Oerlikon – while continuously accelerating.

Circular Economy Campaign

Those who embrace circular economy principles - using items longer, passing them on, renting, sharing, or repairing - help avoid waste, conserve resources, and support climate and environmental protection. But in daily life, this isn’t always easy. Often, people prefer to buy new or leave an unused electronic device to gather dust in a closet. So, do we have a troubled relationship with our possessions? We believe so, which is why we’re sending Zurich locals to couples therapy with their products.

150 Years of ZAV in Four Magazines

To mark the 150th anniversary of the Zurich Bar Association, a commemorative publication was created in an unconventional format: four independent thematic magazines, each written by a different author. JEFF brought these texts to life through concept, layout and illustration, and visually united them as a cohesive series.

anything.

For example, why is rosé more shrimp-colored? Why does a chicken only smile with its molars? Or why are we the way we are? (Spoiler: We would also like to know the last one ourselves.)
