80,000,000 photos in one page sounds a bit difficult to achieve, but the MIT and New York University scientists found the way. The main objective was to manage to fit all the nouns in the English language arranged by semantic meaning (a total of 75,062).

With the help of Google they found photos describing each noun. The sum of all photos describing each noun resulted in a 32χ32 picture. This method was used for all 75,062 nouns and a huge mosaic was made. You can see it here. Clicking each pixel you can see which photos created it and which noun they describe.
