A blind student has developed software that turns colours into musical notes so that he can read weather maps.

Victor Wong, a graduate student from Hong Kong studying at Cornell University in New York State, had to read coloured maps of the upper atmosphere as part of his research.
To study “space weather” Mr Wong needed to explore minute fluctuations in order to create mathematical models.
A number of solutions were tried, including having a colleague describe the maps and attempting to print them in Braille.
Mr Wong eventually hit upon the idea of translating individual colours into music, and enlisted the help of a computer graphics specialist and another student to do the programming work.
‘Three dimensions’
“The images have three dimensions and I had to find a way of reading them myself,” Mr Wong told the BBC News website.
