Fellow Roger Smith, was recently commissioned by the Bodleian Library, Oxford University to build a camera obscura for their current summer exhibition about John Aubrey and the Development of Experimental Science. John Aubrey was, amongst many things, an antiquary, scientist and educationalist - he believed the ideal classroom should contain a set of instruments, including the camera obscura, which would encourage children to learn because it would make learning fun and ' will set them agog'. The exhibition marks the 350th anniversary of the Royal Society, is free to enter and is on until 31st October 2010.
