Have you ever imagined yourself looking like a film star or perhaps a president? Well a new piece of software aims to help you become your favourite celebrity by replacing your face with theirs - but does it work?

Imagine being able to broadcast yourself to the internet but with someone else’s face? Face Substitution is an application that claims to offer just that.

Want to be Nic Cage? Sure! Want to be a terrfying pseudo-Rihanna? Okay! Want to be Bieber for a day? No problem!

Face Substitution can track your favourit celebrities face on yours as you’re skyping away. But is it very convincing?

The app maps your facial features and lighting from your webcam and currently has has 17 different faces for you to “wear” in full Silence of the Lambs mode from The Queen to stranger, more abstract masks like “Picasso”.

It's an unusual idea but is Face Substitution something you would ever use?
