A few figurines hang from the façade of a building on Godefriduskaai. White figures with a square head, that are the brainchildren of artist Daisy Boman. It is an interactive work of art: you can leave a message via an app and then let other people listen to it with a code. The app is free, the message has a small price. There are also general messages that are updated every month. The figures from the artwork here, are enlargements (200 x) of the bomannetjes.
