Lambda the Ultimate

Just came across this discussion of the Deikto component of Chris Crawford's Erasmatron storytelling engine:

Erasmatron 4 is being built around Deikto, a radical new approach to user interface. The concept harkens back to the concepts I originally built into the game "Trust & Betrayal" 15 years ago, but now I am taking it much further. The user builds commands by building sentences on the screen using popup menus.

Not sure if it is really that radical, but I thought it might be of interest to the LtU readership.
