And another artwork based on the procedure (first picture), this time the splits are based on the inverse of the copper ratio (√5 - 2). I noticed that when using this constant, in a tight range of recursion depth, and when rectangles where given 11 different colours, some shapes looked as houses. So I fine-tuned the parameters to get this piece, which I called "Clinging to the hillside" because it reminded me a hillside town. The 11 colours are assigned by an algorithm which computes an integer number for each rectangle based on the size of some of its ancestor rectangles. That number, which reaches the thousands, is then reduced module the number of colours wanted (and picked up from a gradient). Second and third pictures show the result when 10 and 12 colours are asked, the rest of parameters being the same, so different! Also, if the rectangles are given colours depending on the ratio between the horizontal and vertical sides (as with some of the previous artworks), the result has nothing to do with it (fourth picture).
