C's latest project, Grid Owl, is, to start with, a way of displaying, sorting, and searching programming data for conferences and conventions. Events by grid and list. Participants linked to their other events. Auto-generated stats on the number of events, participants, program hours, most used spaces etc.
For logged-in users, events are star-able. Stars create a cluster of other useful tools, from the most-starred events, listed as the convention highlights on the main conference page, to being a personalized schedule which can, in turn, be subscribed to using any calendaring software which can subscribe to webcals. (In other words, the calendar doesn't have to have *all* events - just the ones you're interested in.)
If he gets the map files in time, they'll be linked in too, so that whatever room is clicked on, the user would be directed to the correct map from within the set.
In the grander scheme of things, it's early days yet on this project: he has far bigger plans for what it'll eventually be capable of doing to help with planning conferences and conventions. In the meantime, I'm delighted I'll be able to use this for this year's Eastercon.
