Rokus van Blokland worked regularly at the Sio toy factory in Vroomshoop. There he had his own workshop, along with the modeller Mr Marsman, whose craftsmanship was of great help. Here Rokus could experiment and it was in this freedom he could work on ideas and experiments, not only the design of toys but of these objects as well.
Change by pressure
According to Rokus van Blokland there are a few possibilities to create form; by moving, removing or adding quantities.
In this series of objects he describes form as change by pressure. Pressure is exerted on a pile of blocks on one block per level which changes the shape of both the block and the object. Initially, there is little pressure on only one block. In later objects the pressure exerts on all blocks.
