The real trick is to try and not see faces.
Nice article on pareidolia - or why we tend to see faces where there are no actual faces. From BBC News Magazine:
Most people have never heard of pareidolia. But nearly everyone has experienced it.Read the rest: Pareidolia: Why we see faces in hills, the Moon and toasties, BBC Magazine>>
Anyone who has looked at the Moon and spotted two eyes, a nose and a mouth has felt the pull of pareidolia.
It's "the imagined perception of a pattern or meaning where it does not actually exist", according to the World English Dictionary. It's picking a face out of a knotted tree trunk or finding zoo animals in the clouds.
German design studio Onformative is undertaking perhaps the world's largest and most systematic search for pareidolia. Their Google Faces programme will spend the next few months sniffing out face-like shapes in Google Maps.
Google Faces will scan the entire globe several times over from different angles. So far the programme has pinpointed an eerie profile in Russia's remote Magadan region, a fellow with hairy nostrils next to Priory Road in Ashford, Kent, and a mangy creature in the mountains of Alaska, among others.
It's certainly not the first to uncover faces where they don't actually exist.
