The Moon alphabet was invented by Dr. William Moon (1818-1894). Dr Moon lost his sight completely at the age of 21 after being partially sighted throughout his childhood. He learnt all the embossed reading systems available at the time but found them unsatisfactory so invented his own system. To find out more: http://www.moonliteracy.org.uk/
We have just designed and produced some modular "Moon Signs" for the RNIB Rushton School & Children's Home in Coventry. The signs are designed so when the use of the room changes the Sign can be changed with minimal fuss and cost.
