algorithmic modeling for Rhino
Testing a UI element designed to provide a 5x5 fixed palette of favourite user colours. Cells not specified are interpolated. Not happy yet with the interpolation algorithm, results in muddy in between colours. Cells with specified colours have dots in them. Adjacent cells with specified colours have gaps because there's no interpolation going on.
The Vincent van Gogh image is just a stress test to see if any particular combinations of adjacencies results in wrong gaps and corners.
