Hand drawings populate a universe of possibilities we may call the H-Universe (the universe of  Hand drawings). There too exists an M-Universe (the universe of Machine-generated drawings).

Both of these universes have specific characteristics and both are inexhaustibly mighty and rich.


For the drawing hand, we may list:

  • Every stroke is unlike any other. Only with utmost concentration identical strokes may be possible.
  • Even given a very narrow descriptive “program” for the hand, numerous small deviations are likely and will sum up to have an important impact on the result. The position of the pen on the paper, its speed, friction, etc., as well as the physio-motoric constraints of the hand all contribute to a wide spectrum of expression which is difficult to be cast into strict geometric descriptions.
  • The hand, while engaged in drawing, is under constant control of the eye which provides instant feedback. The spectrum of this feedback ranges from direct control over each stroke to a muffled consciousness about the ongoing action at large.
  • The hand gets tired.


For the machine while drawing, we may list:

  • It is precise, fast, tireless
  • It works with absolute regularity. After thousands of strokes, each next one is like the first one.
  • Irregularities are due to external conditions like a dried pen, paper that ripples, insufficient absorptivity of a paper surface, and so on.
  • Pen pressure, drawing speed, and the position of the pen to the paper stay the same during the entire process.
  • An algorithm is directing the pen. It is blindly followed. The result can be evaluated only after the last stroke has been executed. 
  • The machine cannot evaluate the result.
