           Summary: Negative values for animation-delay are ignored (treated
                    as zero)
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
               URL: http://haravikk.com/#menu
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P3
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: me at haravikk.com


According to the CSS Animation proposed specification
(http://webkit.org/specs/CSSVisualEffects/CSSAnimation.html part 3.8), the
animation-delay property, if set to a negative value, is supposed to start an
element's animation immediately, but from an offset position within the
animation.

For example, a value of -0.4s would create an animation that starts
immediately, at 0.4 seconds until the end of the animation.

The provided URL demonstrates an intended use of this; notice that the segments
of the "wheel" are pulsing in unison, however their starting-frames are
supposed to be staggered so that the pulsing effect will move around the wheel,
starting from "About" and then proceeding anti-clockwise to "Gallery" before
starting again. This can be achieved by using equivalent positive delays,
however 

It doesn't do to only half implement your own standards! =D

Otherwise great job though, the animation's are great.
