Sense of Direction is a property of labeled graphs which has been 
shown to have a definite impact on computability and complexity in 
systems of communicating entities, and whose  applicability ranges 
from the analysis of graph classes to distributed object systems. 
The full consequences of this  property are still not known; in
fact,  the ongoing investigations continue to bring new (often 
surprising) results, to establish unsuspected links with other 
research and/or application areas, and to pose more questions than 
they answer. The aim of this paper is to provide a view of the 
current status of research, describing some of the relevant 
results, and providing pointers to future research directions.
