Small app reproducing the cool SNES perspective effect

Preview:

Perspective equation:

'x = x / z
'y = y / z

More an object is far, more it is small.
More an object is near, more it is big.

Rotation equation:

x = x * cos(angle) - y * sin(angle)
y = x * sin(angle) + y * cos(angle)

This equation apply a rotation on Y axe.
This is the same equation that 3D but adapted for the 2D vectors.
