NEEDLE IN A HAYSTACK: Can you find your face?

The profile pictures of all Facebook users have been brought together on a single page that would take more than 36 years to look through fully.

Miami-based creative technologist Natalia Rojas put the pictures on an online app called Faces of Facebook.

Viewed as a whole, the site looks like television static, but zooming in shows the profile picture of each of Facebook's 1.2 billion users - and counting.

Each face has been added to the site in chronological order, using computer code, starting with Facebook founder Mark Zuckerberg.

As new members join Facebook their faces will be added to the page automatically, with the app giving users a face number.

The only pictures shown on the app are the ones people have set as their profile pictures. No other images are accessible from the site, the Daily Mail reported.

"We are not breaking any Facebook privacy rules because we don't store anyone's private information, pictures or names," Rojas said.

"Because there we are, all mixed up: large families, women wearing burqas, many Leo Messis, people supporting same-sex marriages or [the Muslim Brotherhood symbol] r4bia, Chihuahuas, Indian Gods, tourists pushing the leaning Tower of Pisa, selfies, newborns, Ferraris, studio black-and-white portraits, a lot of weddings but zero divorces, ID photos, faces framed in hearts, best friends, manga characters, politic logos, deep looks, love messages, eyes, memes, smiles, sweet grandparents and some not-yet-censured pictures."
