For best viewing and listening pleasure, use a real c64. This youtube video has been modified in order to allow viewers to partially be able to get an rough glimpse of how the demo should appear in its interlaced color and pixel modes.
It will be more smoother on the real thing certainly (as youtube does not allow 50fps video)
