We were thrilled to get our first "in the wild" collaborator, a group that volunteered to make Braille letter tiles that help kids learn Braille.

We also heard that the first teacher of the visually impaired (that we know about, anyway) printed and used the constant-volume cones. He sent us this picture of the student learning the same way we show us testing it in our video.

Speaking of our video, you can watch it here. Rich used YouTube's captioning tools so as many people as possible could understand what we are trying to do.

Now we will keep publicizing the project and encourage groups wanting a fun 3D design project to jump in and claim a model to do. We look forward to your comments!
