Some time ago I did a progress bar, so I changed it to be used in beamer via the \logo command. The bar overlaps with the navigation symbols, you might want to change it if it is an issue for you:
Code

Edit 1
On popular demand by a single person, I reworked this as it was only "some kind of working". Instead of doing complicated computations with colors now I just use clipping.
RTL progression of the bar now works, furthermore you can influence the position of the percentage label.
