I stopped by the booth as well and had a lovely time there! I am waiting to be told by my school that I have equipment money to spend.... I very much want to see some of your pinhole cameras in my classroom!
I also want to add that in a great many of the presentations I went to during the weekend, there was a great deal of support for maintaining darkrooms in the schools. Instead of the "film is dead" nonsense, we heard that it has its place alongside the all the imagemaking mediums and should not be lost.
