Here’s a Blue Windows 7 theme, I’ve named it Bliss. Contains 9 wallpapers based on Windows 7 artwork, a bluish color scheme & default cursor set with blue ‘wait’ & ‘working’ cursors, I’ve changed the sound scheme to ‘Raga’. The wallpapers are Windows 7 wallpapers with primary color being blue. Here is a screenshot of the wallpapers in the theme pack:

The wallpapers have been sourced from various places & all credit to them & the cursor pack is by UKIntel.
