Anna Carin Hedberg and Ebba Moi initiated a project with us in relation to their sundial art installation at Bakås elementary school. To further the sundial concept, they wanted us to design and produce a small scale production of analog and mobile sundial cases which pupils can use to gain a better understanding of how a sundial works. Additionally we delivered a sign describing the art installations, and a box to store the sundial cases.
Based on specific sundial formulas, a retractable thread is attached to each side of the casing at specific angels. When the sun hits the thread, it will cast a shadow on the numbers engraved in the casing, revealing the time. An integrated compass will tell you where north is - as you have to face north for the sundial to be accurate.
