The largest spring steel mosaic consists of two million pieces. It is a recreation of the Bayeux Tapestry, which depicts the Battle of Hastings in 1066. Each piece measures 7 mm² (0.01 in²), and are offcuts from a patterning disk used on an industrial knitting machine. The mosaic took 25 years to complete from 1979 to 2004.
The pieces are all stuck onto masking tape which was then assembled to metal frames and painted to match the tapestry exactly. The mosaic measures 33.8 metres (110.8 ft) and weighs approximately 230 kilograms (507 lb).
