The Klappermobiel is a musical mechanical interactive installation, based on buzzing cardboard in bike wheels. When you spin a wheel faster, the pitch goes up. So with 8 wheels at different speeds, you can play a musical scale and make songs!

Under the name Studio Knalgeel, Yara Valente and I designed and built the Klappermobiel for Speelklok Museum in Utrecht. It was selected to be exposed here by Springplank, and received additional funding from Gemeente Utrecht.

It is on display at Speelklok from October 1st 2022 until January 31st 2023

After this we would like to exhibit it at other museums, festivals and events, so contact me if you’re interested!
