15. The effects of 12., but clockwise.
16. Only the LEDS in the bottom circle are illuminated. The LEDs
are red, with 4 LEDs in green, rotating in sequence in an anti-
clockwise direction.
17. Only the LEDs in the bottom circle are illuminated. The LEDs
are green, with 4 LEDs in red, rotating in sequence in an anti-
clockwise direction.
18. Only the LEDs in the bottom circle are illuminated. The LEDs
are blue, with 4 LEDs in yellow, rotating in an anti-clockwise
direction (see right).
19. Only the LEDs in the bottom circle are illuminated. There are
red, green, white LEDs rotating in sequence in an anti-
clockwise direction.
20. As 16., but the display moves clockwise.
21. As 17., but the display moves clockwise.
22. As 18., but the display moves clockwise.
23. As 19., but the display moves clockwise.
24. Only the LEDs in the upper circle are illuminated. The LEDs
are red, with 4 LEDs in green rotating in an anti-clockwise
direction.
25. Only the LEDs in the upper circle are illuminated. The LEDs
are green, with 4 LEDs in red, rotating in an anti-clockwise
direction (see right).
26. Only the LEDs in the upper circle are illuminated. The LEDs are
blue, with 4 LEDs in yellow, rotating in an anti-clockwise
direction.
27. Only the LEDs in the upper circle are illuminated. There are 4
red, 4 green, 4 red, 4 green LEDs and so on, rotating in an anti-
clockwise direction.
28. As 24., but the display moves clockwise.
29. As 25., but the display moves clockwise.
30. As 26., but the display moves clockwise.
31. Only the LEDs in the upper circle are illuminated –4 red LEDs
then 4 green, then 4 red etc, moving clockwise.
32. The LEDs outlining the joined circles are illuminated. The
overlap of the circles is not illuminated. The display is red only.
33. As 32., but in green only.
34. The LEDs outlining the joined circles are illuminated. The
overlap of the circles is not illuminated. The LEDs are multi-
coloured (yellow, red, purple, blue, orange etc) –the colours
rotate in sequence (see right).
35. The LEDs outlining the joined circles are illuminated. The
overlap of the circles is not illuminated. The LEDs are
alternately one red, one green, one red, one green etc –the
colours rotate in sequence.
