Kelly O´Connor "Latent" at IGVFest 2009, Dublin
There´s a festival for urban projections since 2006. Stops so far were Florence (Italy), Milano (Italy) and Dublin (Ireland) this february.
This is what they say:
“The International Guerrilla Video Festival (IGVFest) is a mobile festival integrating video art with the urban and social environment. The festival removes the technologically complex medium of video out of the institutional situation re-positioning it as open and reflexive in the public domain. The artworks have site-specific thematic relations to the space where they are shown, engaging and reflecting upon the unique architectural, historical, and interpersonal context of each area the festival travels to.” read more on their website.
The folks at Urban Screen are onto some of the most fluid and architecturally sensitive projections around.
In their words:
“The conception of this project consistently derives from its underlying architecture - the theoretic conception and visual pattern of the Hamburg Kunsthalle. The Basic idea of narration was to dissolve and break through the strict architecture of O. M. Ungers “Galerie der Gegenwart”. Resultant permeabilty of the solid facade uncovers different interpretations of conception, geometry and aesthetics expressed through graphics and movement. A situation of reflexivity evolves - describing the constitution and spacious perception of this location by means of the building itself.”

Found a nice articel about cloud projections here. It´s about Blake gordons photographies showing grafical patterns projected on clouds by citylights. Take a look at the pictures here. When reading the comments for the articel i stumbled upon this clip by Ettubrute on flickr.
First Monday with a Special Issue: Urban Screens: Discovering the potential of outdoor screens for urban society bring together some really interesting articels. These are the topics:

Mr. Valbuena has been deeply engaged in the practice of projecting on things with their shape in mind. From the earlier gallery deployed work to his brillian large scale urban projections like those at the Hague City Hall, he clearly has a way with light and the urban space.
“Ride along with Ali Momeni and his bicycle fleet of mobile video projectors that transform public spaces into eye-popping sound and light shows. Ali’s group, ‘Art on Wheels’ brings ephemeral art to the masses by modifying vendor carts into portable projection systems that can roll to a site, set up and illuminate city walls at a moment’s notice, then whisk away into the night. Also, see the first projector, the “magic lantern,” that’s still in use today.”…taken from vimeo
See more clips and movies of Ali in action at minneapolisartonwheels.org/. or at his own website here.

Back in 2004 Marc Hoepfel from Germany did some nice projections during the Olympic Games 2004 in the city of Athens.
“Lightstrive is a projection in the street. A building is lit by a fast moving light source which seems to bounce in front of the facade. Although it´s light makes jutties and balconies cast dancing shadows which keep sheering in changing directions there is no moving light source to be seen. The only real light source is a video projector opposite the building.”…read more on his website.
