This sounds a lot like what Nate Pagel and Marcos Novak are
working on down here in Austin TX. Marcos is a professor
in the school of architecture here at UT, Nate is president
of local VRASP society. Contact [email protected]

An excerpt of a bygone event below:

>Individuals can be immersed in Novak's 'liquid architectures,' virtual

>The immersed person in Austin can 'meet' the immersed individual in Santa=

>The Virtual Reality
>
>The algorithmically composed architecture of these worlds spans the
>continuum between the solid and the ethereal. Each manifestation has been
>chosen to be unbuildable in the physical world. Spaces exist whose
>boundaries are solid and whose forms are constant; farther along the
>continuum are forms that have been mathematically 'grown;' beyond these
>are forms, still static, that are sculpturally considered mathematical

>architeture, and how we proceed in conceiving and making spaces, but they
>are just the beginning. Beyond these are architectonic manifestations that
>are no longer static, but that move interactively or autonomously. Here
>the architecture becomes a field of elements. Everywhere there is parallax
>and drift, spatial and otherwise, adding depth to the reality of the
>worlds. The entire performance demands a fracture in not only how we think
>of architecture but of the future, Art and reality itself.=20

>Some Worlds:
>A world in which there is a small heart within the center of an
>architectural maze. The heart is an eye and a portal. The whole sky is
>filled with a constellation of hundreds of indecipherable smiles. The
>smiles are calm as long as you stay near the heart, but they spin ever
>more wildly the farther you get from it.=20
>
>A world in which an impossibly slender floating city - formed using
>algorithms that simulate the growth of plants - is found within another,
>vast heart made of bones. If one gets lost in the chambers of that heart,
>one may never find the way out.=20
>
>A world that is cavernous, crystalline, made of mystic patterns within
>which arrays of shapes alternate between algorithmic dances and the
>swimming patterns of schools of artificial subaquatic life.=20
>
>A world that constitutes the first immersive experience of the fourth
>spatial dimension. A series of four-dimensional structures rotate (in the
>fourth dimension, of course) around a vestige of the cartesian coordinate
>system. Their shadows are three-dimensional architectures that enjoy a
>complex but graceful transformational dance. Walls advance gently toward
>the viewer, pass right through, and continue. This world is in constant
>motion.=20
>
>These worlds are connected by portals floating in space, that disappear

>Some Elements:
>A constellation of hundreds of rotating octahedra remains calm when the

>
>An intelligent fog that changes color and density according to the

>A set of 'pulsars,' consisting of a cubic grid of diagonal lines whose
