You may also want to look into Griffon Cloth from Ada Palmer's Too Like the Lightning. Same technology of reactive, digital fabrics which can project their surrounding environment; however, there are instances of non-military/covert use in the series. Notably one of the hives (a nation/culture/society) uses it as a form of self-expression, projecting not a pure replication of what the world around them looks like but an altered version. For example, projecting fantastical creatures into your environment, picturing the city you're in in some specific artistic style, envisioning it as ruins overtaken by plants and time, etc. In this way the human form directly becomes a view into an alternate vision of reality.
