Camera Obscura, Edinburgh

Perched on top of the Royal Mile, Camera Obscura is a great place to see Edinburgh. Visitors look at a white disk in the middle of a darkened room onto which the surrounding area is projected (including all the innocent and oblivious passers-by). There's a voyeuristic air amongst the viewers, as they hover around the images, chuckling as people and things are singled out for scrutiny. There is also an impressive hologram exhibition, which is well worth a look. For the traditionalists, a fine view of the city can be found without refraction contraptions, at the very top of the building. Check the website for monthly timings.
