- I wore a pair of these goggles today for use with a molecular
- modeling program called SYBYL. The goggles are commercially
- available, and need not depend on a specific monitor type. They have
- an internal battery and an infra-red sensor on the face which receives
- signals from a sync device (typically placed on top of the monitor).
- They are comfortable and light-weight, and work even in a well lit
- room (although looking away from the monitor can be mildly
- disconcerting, as there is a barely noticeable strobe effect).
-
- The SYBYL program was running on a Silicon Graphics Iris, and
- the results are truly stunning. The program has a special mode for
- use with the goggles, and the molecules may be spun and rotated in
- any number of ways - and in all instances, the molecules look very
- three dimensional.
