[1][2][3] His works include the following: "Theatre Sculpture", on Canal Road in Brecon, Powys, near Theatr Brycheiniog, was commissioned by Powys County Council and British Waterways, and was unveiled in 1997.

It is made of bronze and stainless steel: a column, height 3.66 metres (12.0 ft), stands on a base with five concentric circles of stones.

There is a hopscotch leading up the needle, made of the various rock types along the coast.

The spheres at the base of the sculpture bear the answers to the riddles, reflected onto the panels.

Councillor Warwick Robinson said: "Although the 'Buttercross Needle' is very modern, its design references well-known local landmarks such as the spire of St Mary's Church in Church Green and the roof of the Buttercross".
