Peepo.com  is a tool for visualisation of complex relationships of real world objects. It uses Go as the delivery vehicle, with each and every element representing data relationships (shadows are stones in atari etc). It is now ready for user testing on 9x9 (best) and full boards (click on the green button for 9x9). It provides maps, hints, comments and score as you play against the pachi engine. It works best with Firefox browser (version 9 or later) and has many features under development.
