Minna Kangasmaa worked at the Lähde! -park in collaboration with the local work rehabilitation centre in fall 2019. As a result of the collaboration the newly built park got specially designed Ripple -railings, that provide support and allow the visitors of the park to do physical therapy exercises. The Ripple -railings signify the unity between water and light. Kangasmaa also supported the founding of a ceramic workshop at the work rehabilitation centre, and guided the participants into the process of ceramics. This work resulted in artwork Spectrum, which is a ongoing communal art project. The artwork consists of multiple ceramic droplets, and each droplet contributes to the colorful composition. The artwork is dedicated to the days when sun is shining through rain drops.
