I ran across this link in my Iceland bookmarks.

It has 360 degree panorama views of Reykjavik, and 5 other locations in Iceland. The view of Reykjavik is taken from the walk around deck at the Pearl. There is a nice cafe inside on this level, which is a floor below the restaurant.

It gives a good preview of a bit of Iceland.
