A Demo by Overflow.
It manages to animate many layers of textured 3D object in high definition and real time on a hardware with no dedicated GPU, to the amazement of the whole modern Demoscene.
Was ranked 2nd at Revision 2017 because obviously a souped-up Sega Megadrive that fails at 3D is more impressive than a CPC succeeding in real 3D.
