So many of the best brands and icons we're familiar with today are cross-lingual, and are embedded in our minds, they were designed so that anyone can recognize & understand them. With these the shape and/or colour alone is enough to decipher what you are looking at.
I took a series of photographs, putting the camera out of focus most of these images are as clear as they need to be to communicate the logo. Some of these are more obvious that others.
Try standing back from your screen, it might take a while to get some of them, if you cant figure it out, click image and read the flickr description for answer.
