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.
Note
If you have an idea of where this panel could stand for exposition, please let me know. A successful lead will be rewarded as follows:
