A giant illuminated star has appeared in the middle of Leeds and the public are being asked to make it shine brighter during its two-day stay in the city's Millennium Square.
The 6m x 6m construction, inspired by the North Star, is an interactive artwork that has been designed by Leeds-based Julia Bickerstaff.
It has been set to mark the launch of the new intercity train operator TransPennine Express (TPE), but the public are also being asked to help illuminate the star as part of a "Where Next?" initiative.
Visitors to the star can write down their hopes for the future of the North and attach them to an LED magnet which will light up the star. Twitter users can also have their messages added by tweeting @TPExpressTrains and adding the #WhereNext hashtag - and the star will get brighter with each tweet.
The 3D structure has been constructed using steel and an array of brightly coloured neon tubes and LEDs.
"With over thirty years' experience working with light, the chance for an installation on my doorstep was an opportunity I couldn't miss," Bickerstaff said.
"The Star is designed to reflect that this is a region that's going places and that people, places and ideas make it happen."
If you want to see the star you'll have to act quick as it will be gone after today.
