What is "720 icons"?

The better way is to have different[rotated,straight & all] icons/images in the resource and use them at the same place.. that would give you an "animated" effect rather than manipulating it at runtime.

What is the icon's dimensions and how often (per-second) does it get rotated?

    // Note - this assumes icon is 96x96 - use the appropriate dimensions when loading the icon with LoadImage()
 
    HICON hIcon = (HICON)::LoadImage(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDI_MYICON), IMAGE_ICON, 96, 96, 0);
    Gdiplus::Bitmap SrcBitmap(hIcon);

    Graphics DstGraphics(*this); // "*this" is the destination HWND

        DstGraphics.ResetTransform();

        DstGraphics.TranslateTransform(SrcBitmap.GetWidth()/2.0f, SrcBitmap.GetWidth()/2.0f, MatrixOrderAppend);
        DstGraphics.DrawImage(&SrcBitmap, -((INT)SrcBitmap.GetWidth()/2), -((INT)SrcBitmap.GetHeight()/2), SrcBitmap.GetWidth(), SrcBitmap.GetHeight());
