I create interactive environments using Unity3d, Sketchup Pro, and Maya. I can create custom environments or re-created real-world locations.

Sketchup Pro allows for fairly accurate recreation of actual places (within an inch or so of actual measurements/blueprints). I am interested in the use of such recreations for architectural pre-vis and planning, re-creation of actual places, psychological applications. 

Here is a link to my example virtual apartment. Doors open, lights turn on & off, and the keyboard plays music when clicked.

Unity Webplayer is required to see it.

The fencing project mentioned here is intended to provide a simulation of an olympic level competitive fencing environment for use in training/treatment of athletes themselves.
