- I have to agree with Mike on this one. Peripheral vision as defined
- by my Webster's New World Dictionary (and how I've always thought of
- it) is:
-
- the area of vision lying just outside the line of direct sight
-
- My own working definition is that something is in my periph. vision if
- I can see it without looking at it. The outer edges of my viewport
- are not in my periph. vision.

- I think Mike really pushed Randy's hot button.
