Leapfrog is Kars Alfrink’s longtime home on the web. Kars is an independent interaction and game designer driven by a desire to help people improve themselves and their environment. He advises on, practices, manages and teaches design. Kars mainly works in software for web and mobile but has also worked in hardware, print, and experiences that take place across media. His greatest pleasure is making tools for play, learning and creativity.
Until recently Kars was partner at Hubbub, a boutique playful design agency, which he founded in 2009. He initiated and co-curated the Dutch offshoot of This happened, a series of events about the stories behind interaction design. He has worked as an educator and researcher at the Utrecht School of the Arts, and before that as an interaction designer at a couple of web agencies.
Kars holds a master of arts in interaction design from the Utrecht School of the Arts. He likes books, coffee, cooking, running and drawing. He lives and works in Utrecht, the Netherlands.
