Aurora borealis waves drift across the room while a field of stars turns slowly overhead. Pick the color, slow the movement down, dim it until it is just a glow — and let the timer shut it off after you have already fallen asleep.

• Aurora waves and a rotating starfield — run them on their own or together.

• 360° rotation covers the whole ceiling, not one corner of it.

• Adjustable brightness and speed, plus a range of color combinations.

• Built-in timer — it turns itself off.

• Remote control, so nobody has to get back out of bed.

Bedrooms, living rooms, game rooms, parties — and one of the few gifts that gets unwrapped and switched on in the same minute.
