Beaufort Sphere 2004 Andy Hazell Beaufort Street, Brynmawr. Beaufort Street is the historical shopping street and the traditional ‘main artery’ of Brynmawr and is central to the Urban Design Strategy. Beaufort Street plays a key role in the economic revival of the centre. Brynmawr is one of the UK’s highest market towns and the project has been designed to capitalise on the windy conditions that the town often experiences, as well as highlighting the link between the street’s name and the Beaufort scale, which is used to measure wind speed.  The Beaufort Street Spheres are the first works in the ambitious Blaenau Gwent public artworks programme. Hazell from Powys was commissioned to build eight polycarbonate spheres, each one metre in diameter.  These are suspended across Beaufort Street, the main road through Brynmawr town centre. Each sphere will have 360 LED lights built in that will light up in sequence to give the illusion that the spheres are rolling up the street.  The speed of the LED light sequence is dependent on the strength of the wind – the harder the wind is blowing, the faster the sequence will be, thus making the spheres appear to be moving faster.
