Great article, I've often considered building a similar interface. However, I disagree with "I don’t care about the past". There are many events which, though they happened in the past, have a direct impact on my future schedule. For example, one of my biggest weaknesses is making sure I've replied to all e-mails which require follow-ups in a timely manner. Lately I've been using Outlook's "Follow Up" flag for this purpose with some success. A calendar program which showed me all of my un-followed-up e-mails, including a visual cue to remind me of how long ago it was sent, would be ideal. Also, ongoing events/projects would benefit from this style. I think my ideal calendar interface would be a screen split into thirds, with the middle representing today, and the left and right sides representing the past and future, respectively, on a logarithmic scale. Maybe someday I'll get around to building it.
