Salford Quays has once again been illuminated by light sculptures as the annual Lightwaves festival returns to the area near MediaCityUK.
The free festival will officially begin on Friday December 6 and remain in place until Sunday December 15.
Interactive installations by an array of artists have been positioned all around the water's edge, many of which respond to audience members' movements.
And despite not being officially underway yet, certain installations were already proving a hit last night, with members of the public big and small riding the glowing musical seesaws outside the Lowry theatre.
The festival aims to bring art out into a public space, making it more visible and accessible to everyone.
At the water's edge across the road from The Alchemist, visitors are able to conduct beams of light using their arms in Light Orchestra, standing on a podium to create your own symphony.
Beneath The Alchemist itself is a slowly-rotating glowing diamond known as Pharos, casting a pink glow over the walls and water.
Then there's the Cathedral of Mirrors inside the university campus building - a dozen huge columns that light up in a full spectrum of colours responding to human movement.
New for this year - and sure to prove popular with families and big kids alike - is Wave-Field, a row of seesaws that burst into sound and light when ridden.

There's also a visit from the world-famous Blackpool Illuminations, who have created Spiro, a wave-shaped colourful tunnel that you can walk through.
Don a VR headset in Geothicket and you'll be transported to a virtual and surreal world of colour - this particular installation isn't suitable for those under the age of 14, or for anyone with photosensitivity.
A new film, co-commissioned by Quays Culture and the University of Salford Art Collection, appeals to Mancunian's favourite topic - rain.
Homage to the Rain has been made up of footage sent in from across the globe of rain in different countries, and is set to an original score.
There's a glowing LED tree known as Digitree, which stands on an LED floor that shows the changing seasons beneath your feet.
Lightwaves Festival 2019 will kick off with The Umbrella Project - a live performance using glowing, multi-coloured brollies - on Friday December 6 at 6pm.
