Switch it on and the room stops being a room. A 360° starfield with nebula clouds moving slowly across the ceiling and down the walls — the whole sky, not one bright patch in the corner.

• 360° coverage — ceiling and walls at the same time.

• Star layer and nebula layer, run together or on their own.

• Astronaut helmet design that looks good switched off.

• Bedrooms, parties, or the background of every video you shoot.

The reason people film their ceiling and post it. Now it is yours.
