Inside the Academy is a single large room. On the walls all the way round this room is the complete ASL alphabet, with each letter printed large and clearly, with a corresponding picture next to it. Clicking with whatever pointing device you are using to access the VR world (mouse, 3D pointer, glove, etc) will open a new window in which a dictionary page gives you further explanation, and the option of a Quicktime movie of a hand creating all the movements for the letter.
All this is just instruction however. The real purpose of this Academy is in the table in the centre of the room?
