Argos is a high street catalogue shop in the UK. One of their lighting products is the rather splendid Laser Sphere. A light that has 9 LEDs and three lasers mounted behind a rotating lens with a random pebbled lens effect that creates a continuous slowly morphing aura effect with three red laser "entities" that warp about over the aurora.

It's a great effect, but is let down slightly by the accuracy of the plastic moulding that can make the lens shaft very stiff and the lens itself may hit the cover as it rotates. You can improve the movement greatly by loosening the screws on the shaft support and also on the motor itself.

The motor is a synchronous unit that runs on 12V AC and is very slow and quiet. It's not got a specific direction.

This light is being sold off at a reduced price as of August 2019 (getting hard to find as I type this). It's worth buying one for the lens and motor alone. The product is quite mature, so in this era I might have considered using 1W LED chips for a brighter effect. Target price online is around £25 or less as I see a lot at very inflated prices.
