The existing Xscreensaver flying toasters is a sort of clone or reimagining whereas this new one looks like its exactly the same as the old After Dark Flying Toasters.
The original screen saver is still covered by copyright for at least 61 more years, and Berkeley Systems previously sued the makers of an Opus and Bill parody screensaver. So it is understandable that xscreensaver doesn't have a faithful replica of the original.
