Numeric Patterns Part 2

I tried to expand my numeric patterning  and found another technique that is able to make patterns from numbers which is more obscure than the previous technique. I believe this patterning technique will reflect memorability of a number in a better way. I still need to do a survey though. The detailed description of the algorithm is a little complex and also boring, so I leave it to the code readers. Nothing special in the algorithm.

The images are generated with Processing language. The sketch is here (Data_Painting_Part_2_pattern_and_number.rar). Download it, edit the text file 'data.txt' and run the sketch. The sketch will generate images of the numbers in separate .GIF files in the Images folder.
