Still going - this is worth a bump.
Jolly useful for anyone with a laptop who switches between using an external monitor, the laptop screen and projectors, all of which tend to need different resolutions.
As well as absolute icon positions it will keep relative positions, which is better.
Does other fun things like hide all desktop icons if the cursor isn't there, makes the active window transparent so you can see what's underneath, change icon label text colours....
Works with XP, Vista and 7.
Haven't tried it in conjunction with any multiple desktop managers such as Dexpot.
