2. Eric Martz's DNA tutorial, which is truly non-linear. Buttons, which are presented in a panel rather than interspersed with text, can be clicked in any order. I am not sure how Eric implemented it, but I know it was a lot of work.

Correction: Rather than always producing the same image for each button, regardless of the order in which buttons are pressed, this DNA Structure tutorial takes a quite different approach.
There is no specified order to the buttons (hence I have described it as a "nonlinear" tutorial). The image produced by a button depends on which buttons were pressed earlier. For example, pressing the [Bases] button while the DNA double helix is showing highlights the bases throughout both strands, but pressing it while a single nucleotide pair is showing highlights the bases in that pair. Pressing [Spacefill] spacefills whatever was most recently highlighted. And so forth.
Unlike the traditional tutorial, this tells no linear story. You have to choose an order of buttons to press (or else nothing happens), and each person may follow a different path, learning in a different order.
Yes, this required a lot of extra programming effort.
Yes, there is a development interface and instructions included, and the whole thing is downloadable. So far as I know, nobody else has ever used it for a new tutorial.
