Google Calendar entries for a number of days (from current day only - or possibly current half-day only).
To be shown as a list of 1 or more scrolling (if necessary) entries or as a ticker. With configurable display elements date, time, title, description, where. Also configurable separators (like your ticker).
Example 1: I would use it for a "Welcome" list of today's (or morning/afternoon) visitors.
Example 2: Also for a list of upcoming exhibitions.
Using google as a source of times events allows anyone with access to that the ability to make Yodeck entries without getting into your quite techy front-end.
I can deal with the layout - they can deal with the content.
Thanks for listening.
