Scott Wallace has a "watch it" context menu item in his images that does exactly this. E.g., you simply select an expression:

	ActiveHand position

and choose "watch it" from the menu, and it creates a simple updating string morph.

(similarly, there is a "button for it" menu item that executes the expression once when clicked. very convenient)
