We used the Kasperg Falling water HL2 engine model of Frank Lloyd Wright's Falling water as our exemplar real-time Architectural visualisation in last sessions Collaboration Studio. Digital Urban reported on a nice new (non-real-time) visualisation of the same architecture for us. Though it isnt real-time, it does tell a nice story particularly in the first part.

This sort of digital representation isnt new, but should still help to win over those who shy away from the digital realm. Interestingly, this visualisation of FallingWater makes it feel quite light and airy actually. This contrasts, for me, with the experience via the Kasperg model where the building feels rather heavy and closed - interesting. The Digital Urban blog has a vid of the Kasperg model as well.
