As a child, Matthew Shifrin loved building Lego sets. But Shifrin is blind, so he had to rely on friends and family to help him complete his creations.
That changed when he was 13 years old. A family friend came over to his house in the US state of Massachusetts and handed him a binder filled with accessible instructions for building a palace.
The instructions were written in Braille, a writing system understood by touch. It allowed him to complete the set without having to see the brightly coloured pictures that usually come with Lego sets.
Three years ago, Shifrin launched Bricks for the Blind. The NGO creates downloadable instructions that are free for anyone who is blind or visually impaired.
