Where the drawings come from?

A lot of people has been asking me about how I'm using Windows GDI for drawing.

In fact, I'm using my own rendering engine. I'm improving it step by step to be able to draw complex antialiazed shapes/figures.

There still are countless tools to code: hierarchies, complex shapes, transparencies, gradients, blurring, etc.

But the P2P project is going on ... since November all screenshots were drawn using my engine.
