In the flurry of activity on Pi day I took the opportunity to make two visualisations based on others I had seen floating around. This one assigns a color to each digit of pi and then creates a square pixel and stacks them in towers to completely fill a 1000*1000 canvas. The size and hence number of digits processed is contoled by the point_size node.
The best way for me to associate a number with a colour was to write my own python node that basically uses a dictinary to look up items. How could this be achieved with the existing NodeBox nodes?
Attached is the .ndbx file and the .py file the .csv file of pi digits and and an example rendering.
Comments very welcome
