I have a simple dashboard for project managers. It's intended to give very basic information, and to give them a "launching point" to get to all the most important things they need to take action on. Here is a screenshot where the data has obviously been washed, but the look is exact.
I have had a lot of people say it works great for them, but others say it's a lot of information and it kind of "washes out", i.e. they are a bit overwhelmed and it would be helpful visually if there were elements that could break up or somehow enhance the screen visually without cluttering it more.
I forgot to mention that when a user clicks into one of the dashboard sections, or clicks on the + symbols, that section expands to fit as much of the content as it can without scrolling, and the other sections contract. Also, this is all designed to fit on one page, with not "page scrolling", though there is scrolling for the grids themselves when there is more data than can be shown.
