You might remember, about this time last year, gawking at the mesmerizing Troika illuminated signage erected in the V&A museum's tunnel entrance.

Well this year, Dutch electronics giant Philips have added to the lighting display with an interactive installation in the same tunnel—and another hidden away in one of the lesser know gallery spaces of the vast Victorian edifice.

"Walk The Light," a collaboration with Domonic Harris and his Cinimod studio, illuminates unwitting V&A visitors with a trail of bright white light and a spectrum of colour that transitions from a cool blue to a intense red as they approach the museums door.

The effects were, of course, absolutely top notch, but, we're sorry to report, this particular installation disappointed quite significantly by being entirely baffled by the almost constant stream of visitors passing in both directions through the space.

"Ice Angel," also the creation of Dominic Harris, in a much quieter gallery space, was fortunately much more succesful— the interactive led display transforming anyone waving their arms in front of it into a glowing angel. We're delighted to bring you this fabulous demonstration courtesy of a kind, if slightly confused, Spanish-speaking V&A visitor.
