The incredibly serene mood combined with late-90s tv-funk music put me into a weird state of nostalgic careless bliss. (As opposed to the more typical nostalgic feeling of unrecoverable loss.)
Speaking of nostalgic bliss, Infochammel does this for me. With its HC2K TechnoLoc encoding I get a strong dose of positive vibes reminding me of my Apple IIgs and childhood. I'm a huge sucker for that style of graphics.
