Yesterday learnt a little more of the GDI+, drawing lines from points and arrays of points, drawing ellipses using drawing lines and drawing ellipses which uses a rectangle. Drawing arcs and pies. That kind of things doing little programs as I went. Also went through Lights in my D3D book. Good but I need to apply it :).

Most cards support only eight lights at once! I guess if you had a level, you turn some off and on, reposition them as you go so it appears there are more lights than there are.
