Matthew Shifrin works to make LEGO kits accessible to blind people. Along with help from his family friend Lilya Frinkel, Shifrin became an expert LEGO model builder, developing a scheme to translate visual LEGO assembly instructions into Braille. Shifrin wrote:

Lilya could make just about anything accessible for the blind. Making things accessible was a challenge she enjoyed, but LEGO was different. It was impossible to Braille the blueprints. The instruction manuals had no words, and they were too complicated to be turned into raised-line drawings. Building a model required so many steps that I couldn't copy them all. LEGO was the only thing that stubbornly resisted adaptation.

Or so I thought.

For my thirteenth birthday, Lilya had custom made instructions for the Battle of Almut, a Middle Eastern domed castle. How had she done it? Where did she find text-based instructions?

It turned out that she didn't find them--she created them! Lilya wrote out the instructions step by step, describing every blueprint, giving names to every kind of LEGO piece, figuring out the most logical sequence for a blind person to follow. She also sorted the LEGO pieces, putting the pieces necessary for each step into a Ziploc bag and labeling each bag in Braille.

Shifrin has begun posting these instructions on his website.

In this 13-minute documentary, Vanessa Hill visits Shifrin to explore his work. This is not just about LEGO, it's about spatial perception, which is fascinating stuff. If you're sighted, keep an eye out for the Braille display Shifrin uses—that device pops up one line of Braille at a time, and along with the attached keyboard, allows easy access to long sets of Braille instructions.

If you liked that, you might enjoy this outtake video in which Shifrin's screen-reader reads out 10,000 digits of Pi from a YouTube comment. (Then he flips it into Russian mode and does it again.) This is a nice mini-demo of how screen-reader software works, even for silly stuff like YouTube comments.
