Minneapolis-based artist and musician Sean Connaughty has done many wonderful and interesting things. Among them are a series of self contained ceramic biospheres that he sculpts, fills with plant life, and then submerges in waterways to become free floating universes. He wires them with cameras so viewers can hit his website and see what is going on inside. Now he has taken on his biggest version of the project yet, a massive concrete ‘Ark’ biosphere which will be submerged in Lake Superior near the Aquarium. The image is of the Ark being hoisted in place for the Northern Spark Festival in June at the Weisman Art Museum in Minneapolis.
