Matthew Shifrin, a blind musician and activist, has been a motivating force behind much of Lego's decision to make its bricks accessible.

As it turns out, Alexx followed up on the marvelous toy suggestions

and managed to locate my marvelous toy, which is called a Quix
http://www.amazon.com/Quix-Space-Changers/dp/B003G79QVI
which is also referred to as a "sculpture toy."

Coincidentally, one of the artists I have been intrigued by lately is
Alexander Calder
http://calder.org/life.html
who was known for making wire sculptures from hardware store wire and found objects

although he is also famous as the inventor of the mobile: "The name "mobile" was given by his friend Marcel Duchamp, a perfect description for the abstract, airborne sculptures that Calder liberated from 'mass,' incorporating movement as a "material" itself for the first time. The sculptor described it as 'drawing in space.' " [quoted from the above-mentioned Web page]
That quote from Calder about using wire as a means of drawing three-dimensionally makes him particularly accessible to talking about art for blind people.

Calder is also famous for his toy circus made up of moving wire sculptures. You can watch a video here
