Windows 3D Movie Maker?! I did not know such a thing existed... I loved their regular Movie Maker, that came with Windows XP, or was it 7... but apparently that goes way way back! And it seems like the originator was even more fun the one I was introduced to. They've streamlined it too much since; lost the charm entirely...
I don't recognize this theme thus but it's a catchy one, and well-played. Glad you introduced me to that unexpected old gem of Windows history too.
