If you’re travelling via Kings Cross St Pancras station this summer, chances are you’ll walk past about 10 metres of yellow and black balls that make up Songboard.

Of course, if you just look at it, you’re missing half the fun. The 3,000 balls can all be moved in half-turns to show either their black or yellow sides and when you flick the right ones around, they make a sound. According to Chloe Meineck, one of Songboard’s designers from Central St Martin’s College of the Arts:

Around 300 of the balls are musical; when turned, the ball sets off an individual section of music, it could be a recording of Big Ben or a musical note. Meaning that songs can also be made with a group of friends playing with the songboard.

Songboard is one of the Mayor of London’s Wonders, part of MoL Presents: A Summer Like No Other. Have you spotted any installations such as the Gifts from the Gods or the Universal Tea Machine at Victoria Park around town this summer? Let us know in the comments below

The smart jewellers of Bond Street, Conduit Street and Grafton Street in Mayfair have allowed students from the Royal College of Art and Central St Martins to take over their window displays for a week.

At a private view last night, top-end jewellery shops such as Asprey, Chanel, Cartier and Tiffany were full of students and tutors from London’s top art colleges.

My highlights included a display of intricate paper bees; a rotating case with magnifying glasses trained on a diamond bracelet; and an interactive TV screen where you could see yourself in a princess-like tiara.

The Street Lights project runs until 15 May 2011

Sad news yesterday: London designer Alexander McQueen was found dead at his Westminster apartment.

The so-called the bad boy of fashion, Alexander McQueen became a hugely influential force in the fashion industry, and his death is being mourned across the world.

He was born Lee Alexander McQueen, the youngest in a family of six kids, the son of an East End cab driver. Schooled in Stratford, McQueen remained proud of his working-class London roots. At the age of 16, McQueen began working as an apprentice at Savile Row tailor Anderson & Sheppard, then moved to Gieves & Hawkes on the legendary street. He also worked at Angels and Bermans, theatrical costumiers on Shaftesbury Avenue. In the 1990s, he completed an MA at Central Saint Martins.

In many ways, Alexander McQueen’s styles were typically London: rebellious, irreverent, creative and pragmatic.

US Vogue Editor-in-Chief Anna Wintour called McQueen “one of the greatest talents of his generation.”

“He brought a uniquely British sense of daring and aesthetic fearlessness to the global stage of fashion. In such a short career, Alexander McQueen’s influence was astonishing – from street style, to music culture and the world’s museums,” she said in a statement. “His passing marks an insurmountable loss.”

His death comes just days before London Fashion Week, where he will be sorely missed.
