I might get myself in trouble posting today's blog - because you are not allowed to take photographs in the Serpentine Gallery.

But what the heck, I think the current exhibition, which closes on 3rd February, is so brilliant I urge you to go and see it.

In a darkened room three dimensional light beams are projected. Standing enveloped by the light you can see the swirl of patterns generated by a smoke haze.
