Road trip of wood PRD, first prototype

Maria01, Ruoholahti, Helsinki, June 2019

The so-far-mobile panel has moved – from its wheels – to be wall mounted. Maria01 is a growing-ground platform for start-ups. One could say, a businesscenter-like forum.

Studio, Vallila, July 2017

In studio of Aki Päivärinne. Vallila, Helsinki.

Here, the same type of panel as mentioned above (PRD) is colored by spray paint and a photo of a guitar has been added.

The very first proto work – the spray painting was not a success.

Note: the video opens up in a new window.




The 2nd pilot test, on a Green guitar theme. Tolerances not yet pleasing the eye… as can be seen.

That said, the 3rd panel (see references) is made using a custom built cutting table.
