As the pendulum swings back into Second Life for some exciting new consulting projects, I’m reminded just how fun it is to build with prims and how much potential virtual environments hold for architectural practice and collaboration. You can quite literally *feel* the space as it takes shape, understanding and perceiving it in a way that no other medium affords. It’s somehow subtle and elegant in the way the virtual design experience retains the serendipity and chance of crude cardboard study modeling yet enables just enough of the precision of a 3D modeling application – but not so rigid and exact as to zap the design flow of its creative energy.
