Nathaniel S. H. Brown - DateBocks, the new, intuitive date input selection for your forms:

"We use common terms in english to express how we identify a date coming up, or a date in the past. Such as “Next Tuesday”, “Last Month”, or even as simple as “Friday”. We clearly know which date that identifies, but until now, a computer had no idea, as far as forms were concerned."

Reminds me of what I read about Lotus Agenda.
