Excel Progress Indicator & Check-List Proof of Concept

Recently I was asked by the project management of a client to create a check-list in Excel for an initiative they are heading. While I cannot disclose the exact solution I provided them — due to non-disclosure agreements in effect — I can share the proof of concept I built for the spreadsheet. As a part of my brainstorming about what would be useful in such a spreadsheet, I devised a rather novel progress indicator which updates automatically as tasks are completed.
The proof of concept spreadsheet can be found hererent a car bulgaria. Credit is due to the guys at Juice Analytics???????? for pioneering the concept of representing values graphically within a cell.
