Author here. Very flattered for the comment about the WiiMote demo, as it is very much an inspiration and indeed an impressive and groundbreaking demo.
The key difference here is that in the WiiMote demo, the head-tracked location is used to shift the camera perspective so that 3d objects appear to have additional "depth"; whereas in anamorphic projections the effects of perspective are deliberately undone so as to flatten the image and appear to have no depth at all.
In the end they both use the same technique, but end up with different a outcome/effect. :-)
For what it's worth, I find it generally useful to have a google calendar open in my browser at all times, so having additional information available without having to drill down on individual appointments is delightful to me.
Agree though to the 48-hour limitation -- would be great to one-click side load appointment information for any day of the week, not just the next two days.
Feature request: Would it be possible to make it an option to "minimize" or adjust the width of the sidebar to the right? Works great when google calendar is full screened on my 1920x1080 monitor, but screen real estate can quickly get cramped on anything smaller.
Otherwise, a great start -- I absolutely love that a little map shows up for the next appointment, wanted this for years.
