Projection mapping offers exciting opportunities to animate and alter our perceptions of a physical space through light. More often the physical space projected on to is buildings with mesmeric light sequences and often contextual narratives.

Much like Louis Daguerre & Charles Bouton achieved a sense of movement through altering the play of light on a large transparent screen with the Diorama in 1822, projection mapping can create this immersive and moving scene onto any 3d object or screen. Through altering the play of light with large amounts of lumens generated by today’s digital projectors, artists and designers can become the theatrical painters without being limited to dark purpose built venues and opaque or translucent paints, instead projections can be achieved in other lighting situations with custom built screens & pixels.
Dalziel + Pow have moved the play of light onto a physical map where they experiment with different narratives using the terrain of Berlin to abstract and segment their sense of movement. I like the idea that with this being an indoor permanent installation the growth and development of the narratives can evolve and change from the projection mapping unlike many projection mapping spectacles that are single events. It is exciting from a data visualisation point of view to see how they could experiment with this, ‘expect to see dynamic data and live online feeds added in the near future.’ (Dalziel and Pow, 2015).
Dynamic data could be live narratives from geotextual tweets, visual iconography of weather, real time data of subway, air or live visuals with imagery of scenery, architecture that are geotagged within the framed boundaries of the physical map then abstracting into their segments in a realtime collaborative cartophoto-montage.

It is exciting to see how this art form will evolve with physical cartographic representations and their inter-play with light immersing us through digital mappings.
