Indeed, thanks! I can't see your pictures there but that GIF is definitely what I'm seeing here as well, albeit without any progression.

The black display is damn nice :-) I have a 39gs somewhere without any actual use that I might sacrifice without much grief. Is its display compatible with the 48?
