According to Adweek, the bricks feature raised studs à la Lego bricks, but with a twist: Those trademark bumps are arranged in patterns that conform to the braille alphabet (which uses a 3×2 post pattern, just like Lego bricks).

The tool has been developed by the Dorina Nowill Foundation for the Blind and designed by creatives at Brazil advertising agency Lew’LaraTBWA.

The process of creating the toy/tool took about a year and when it was completed was presented to blind children aged seven to ten. The results, filmed for a mini documentary, shows the reaction of the kids, and is, for lack of a better term, totes adorbs.
