As of 2011, Mąciwoda has been collaborating with friend and fellow musician Efrem Wilder in the outfit Stirwater. The name Stirwater is derived from the English translation of Mąciwoda last name "Mąciwoda". The collaboration between musicians ended after a couple of years but they managed to get a single recorded. It was called "Water water" and it was number two for a couple of weeks on the Polish radio station Trójka in the summer of 2012. After that the band broke up but the project Stirwater is continued as he is playing and recording with fellow musicians from all over the world e.g. Florian Hofer from Germany or Atma Anur from UK.
