“you’re not at Virgin Megastore”
I’ve plugged my favorite photohosting site, flickr, a bunch of times. I think one of its greatest characteristics is the ability to just browse through pictures of any kind of subject imaginable. Just come up with a tag name and look through all photos with that tag and you can get ideas for how you might design a pergola, see pictures of a red panda, see what Red Square looks for an upcoming trip, or find mood pictures like funny or sad.
You can also find some fascinating pictures like those tagged DPRK (Democratic Peoples Republic of Korea, or North Korea) or 2008 Olympics. Really fascinating…
