Gestalt won the 1st prize on FindLab Contest in Guimarães Capital of Culture 2012. Made out of cork, the main idea was to use a symbol from Guimarães ( "Cantarinha dos Namorados") and play with their perception, bringing the Gestalt Theory. The vector silhouette  output from the Cantarinha generates the whole piece. You can only perceive the full silhouette on certain points of view.
