If you haven’t yet heard about ffffound.com, consider this post a gift from me.
From the site:
FFFFOUND! is a web service that not only allows the users to post and share their favorite images found on the web, but also dynamically recommends each user’s tastes and interests for an inspirational image-bookmarking experience!!
Seriously, have a look. If you’re at all into photography, or art in general, or even just beautiful, interesting things–you’ll love it.
