...make rounded windows?

// The CreateEllipticRgn function creates an elliptical region.
function CreateEllipticRgn(
nLeftRect: Integer, // x-coordinate of the upper-left corner
nTopRect: Integer, // y-coordinate of the upper-left corner
nRightRect: Integer, // x-coordinate of the lower-right
nBottomRect: Integer // y-coordinate of the lower-right corner
): HRGN;
// The SetWindowRgn function sets the window region of a window.
function SetWindowRgn(
hWnd: HWND, // handle to window whose window region is to be set
hRgn: HRGN, // handle to region
bRedraw: Boolean // window redraw flag
);
// Example:
procedure TForm1.FormCreate(Sender: TObject);
var
hRegion: HRGN;
begin
BorderStyle := bsNone;
hRegion := CreateEllipticRgn(1, 1, 200, 200);
SetWindowRgn(Handle, hRegion, True);
end;
