Today I scaled up the testing of the data flowing over rubber surface. By moving the projector back further and adding more rubber to the surface and area of around 2 x 1.5 m was tested to good effect. Scaling up brought some issues like focus of the projector but ton the uneven surface this is lost.
I believe for the final installation an area around 2.5 x 2.5 m will be sufficient to achieve the effect desired. Testing element lying within the landscape was also interesting and these provided a narrative or points for the audience to explore and investigate.
