So I took the last 2 days to make this mockup- some things still arent done/ I deleted-
1) Needs Nautilus menu Icons
2) Needs Close/Min/Max Icons
3) Needs a unified Icon set- on that is glassy and transparent
This theme changes with the background, so different backgrounds give it its own theme.
PS: The one with the Hardy background is further along in refinement.
Compare with OS X and Vista.
