Bigert & Bergström: Solar Egg, pubblicato da Art amd Theory, è dedicato all'opera d'arte degli artisti svedesi Mats Bigert e Lars Bergström, che è allo stesso tempo una spettacolare opera d'arte pubblica e una sauna perfettamente funzionante. L'affascinante libro illustrato parte dalle fasi dell'opera d'arte, un uovo d'oro chiamato Solar Egg, e va dagli schizzi all'opera finita.

While the works of Bigert & Bergström often touch on serious issues of social and environmental sustainability, humour plays an essential part in their practice. The idea for the ‘Solar Egg’ arose from the ongoing geographical repositioning of the city of Kiruna in northern Sweden. It is a fully functioning sauna, developed as a public artwork that would engage the community of Kiruna and is to be seen as a platform for discussion as well as a place for reflection. This book chronicles the making of the artwork from rough sketches to the final piece.
