Instructions:
In the frame on the left, select Plan 1, Plan 2, etc to make the respective floors' plans appear to the left (click again to hide them). Mouseover the areas of the plans for links to pictures and information of the respective area, which will appear in this frame when you select them. The blue Q's are links to 360 degree Quicktime Paoramas, which also appear in this frame.
The + and - controls are for zooming in and out, the hand allows you to shift the focus of the view, but remember to click the black arrow again after using those view adjusters so that the mousover links will work again. "R" will reset the floor plan's perspective.
Finally, you can grab the center bar between between the frames and slide it left or right to make either frame larger.
