What are the doodles?

The so-called doodles is a little collection of my so-called "art". Well, it isn't art really, but more of yet another form of activity.

Although it is mainly about the drawings I make, I decided to also add more "art"-related things. The first doodles actually came from the school time, where I used to spend the precious time filling the last pages of my notebooks with simple graphs. When my notebooks went full, I used to borrow my friends' ones and did the same. With time it developed to the effect you can see here. They are not professional pictures, but I hope you'll enjoy.
