Here is an HTML5 pano sequence from Vienna, near the Donau canal, showing buildings by Hundertwasser and Hadid. Her buildings have almost no vertical walls and the panos were a bit of a problem to level (thanks Bernard!). More from Vienna to follow.

ps
The one thing I miss on converting to HTML 5 is the lack of lables on the hotspots - any info happily received!
