Here is a NY TImes article about using special lego blocks for teaching Braille.
Braille is based upon the combinations of the presence of a bump in any of six positions. The most common lego block size has 8 bumps.
Six of the bump positions are used to encode the Braille while the rest of the space in the 8 bump sized block is used for a visually printed letter (for visual readers).
I think this is potentially a brillant idea for teaching Braille, which many blind people do not read.
This idea is being tested in a few countries and will be soon tried in several others.
