A shape-shifting laser "Star of Bethlehem" has been installed at Salisbury Cathedral.
The geometric star, made by focusing two lasers onto a transparent screen high above the nave, was created by coding artist Jayson Haebich.
Cathedral visitors will also be able to manipulate the colour and shape of the "modern-day" star by using an iPad.
Mr Haebich, said it was designed to act as a "guiding light" and "draw people into the centre of the cathedral".
Created in response "to the theme of the Star of Bethlehem", the geometric star shape has been set up to change gradually over time, evolve and never repeat the same shape.
Mr Haebich, its creator, said: "The star itself rotates and morphs and at certain points within the day - there's an iPad set up for the public to come and use so they can interact with the shape - change the colours and play around with it."
The cathedral said it is also "exploring the installation's full potential" to see if it could be used around the Darkness to Light Procession at the end of November, which marks the start of the Advent.
