A visual family tree of the panoply of Greek gods, from Chaos to the Olympians and beyond, appears on a handy webpage with a graphic made from a PowerPoint file created by Ivan Kozik, a USA programmer, using Wikipedia as the source information.
 
The ppt file can be downloaded, amended and resent to Ivan for uploading.
 
I looked into adding Daemons, and in particular Agathodaemon - spouse of Tyche, but on a Mac using Keynotes I could not find room and thought that changing it from .ppt to .key and back again was impolite as that could introduce formatting problems.
 
STOP PRESS: Ivan has just given permission for SalvoNEWS to turn this into a collaborative Google Doc which can appear on the web, all of which should happen soon.
