The 5th part is missing/not working. In the boot part, use Joystick from port 2. Select the number of the part you'd like to see, and press the fire button. When a part is on the flip-side (the top/right corner displays Side 2), insert/attach that side, otherwise the demo may hang.
The raytraced animation in the 7th part is converted from the C=64 demo The Last Traktor III. (See an animated comparison here.) The same animation was also converted in Now & Forever.
