We are gratified that we have so many people following this project. Our Google Group is out there with a lot of teachers of the visually impaired asking for models now. However, there has been very little fulfillment of requests. Unless something has a stamp "fulfilled" it is up for grabs! (Or if you have a cool model and it's been fulfilled, post it anyway. Why not!)
As a reminder, here's the group. Instructions are linked there, if it's been a while. Also, if you are interested generally in math and science modeling, check out our progress on this year's prize project, Hacker Calculus.
