2016 – Actuated Prism Map of Italy
This actuated prism map was created by Alessandro Masserdotti in the OpenDot Fablab in Milan, Italy, for the SOD16 meeting and invites people explicitly to Touch That Data. OpenDot Fablab (Milan) project with Arduino and 3D printing visualizes regional statistics changing the height of each region. In the picture there's the building count from the regional extracts.
