Holidays Meetup: Tiling WFS, Unified Map Service, Expressive Styling, 3D Cities

I will have some cool demonstrations about our vector tiling, tiling WFS (serving up a street map of the UK for the whole of Great Britain), unified map service and visualization of 3D cities on which we have worked hard the whole year, and per Regie's request we will get into the details of a proposed rule-based cascading map styling language we are proposing.
