Mosaika is a sound and light show that tells the story of Canada. It is quite clever in its use of the Parliament centre block building as its screen. You can read about it here. The image below links to a clip of the show that I shot one evening.
It is quite the spectacle. It ran over the summer months, ending Sept 3. Perhaps it will run again next year, in which case you should make a point to see it if you are in the Ottawa area.
