PenSpinning is a sport for programmers!

What is PenSpinning? It can be said, a kind of sport. The “handle manipulation” is correctly translated into Russian. It itself appeared relatively recently and is not widespread in Russia, although in Asian countries it is developed very well.
Probably, everyone, sitting at a time at a lecture, began deliberately or involuntarily twisting the handle in his fingers - this is what is penspinning. The thing is not what and where to turn, but how :) This activity in itself helps not only to pass the time, but also gives a lot of pleasure, moreover, with proper training from the outside it looks very cool! There are already several communities of penpinners in Russia, and their skills are really worth seeing. By the way, in terms of the number of modding handles options, this “sport” gives one hundred points ahead to any other, for example, street racing!

Well, for warming up, an example !
