Hi guys,
Just a quick design criticism. The current admin bar looks great on light backgrounds, but when it's on top of a dark background it looks pretty weird and the intended effect of it being 'beneath' the page is completely lost — instead it just looks like a poorly shaded bar.
I would advise taking a look at how Twitter does its exceedingly similar bar, as all sorts of different backgrounds are shown on Twitter and they've very carefully tweaked it to look against all. Specifically, they use a broader gradient and have a subtle drop shadow beneath the bar.
