Not to worry KJP. Now that I'm plugged in, I plan to be very active. Thank you for the warm welcome.
Several of the earlier posts were discussing Hilton's sensitivity to context. In my opinion, CooperCarry not only does a great job of contextual design, but their building pays true homage to its neighboring traditional buildings at the mall/pedestrian level by reflecting those structures in its glass curtain wall. Then, as the building progresses to the skyline/distant view, CooperCarry modifies the visual language of the curtain wall, leading the eye skyward with a streak of light and finally tilting the building toward the mall as if bowing in the prescience of the greats of architecture's past.
That final bow, represented by the tilting top becomes the signature statement on the skyline that seems to say "while I bow in the presence of the greats of the past, I assert myself as the future."
