In the Barbican lecture hall I caught a glimpse of a man with the most interesting hair, he must have let it grow long all over and the had it sculpted like a topiaried box hedge. The dark angular shape stood out against the sculpted white plaster wall beyond making such a strong image that I felt I must attempt to record despite the fact that everyone was rising from their seats and pushing past. It was a fleeting moment and I only had a mobile phone, the low light and the urgency made for a blurry result.
