AMMDI is an open-notebook hypertext writing experiment, authored by Mike Travers aka mtraven. It's a work in progress and some parts are more polished than others. Comments welcome! More.
Interestingly parallel with Promethea, by the other genius-level English graphic novel author, Alan Moore, which is also explicitly about the imaginal.
Another parallel: the last half of the Sandman run involves (spoiler) the death of Dream, because the Endless can die and there is even some metaphysical machinery to handle it (see the Litharge story in World's End). Recall's that line in Watchmen "I shall go tell the indestructible man that someone plans to murder him"
