When Japanese artists Teruyuki and Yuki Ishikawa revealed a photo of their 'daughter' to the world last year, she looked like an ordinary schoolgirl. However, Saya is no normal child.
She is a computer generated 3D model - and over the last 12 months the couple have been improving and updating her.

The 3D CG artists, who have made the improvements in their spare time between personal and commercial projects, have matured Saya's features and fully animated it using a motion capture process. This means that the duo have recorded movements of a person and used that data to animate Saya. Think behind-the-scenes of Lord of the Rings or Avatar.

The model's features - especially strands of hair, eyes and skin - are so human-like you'd be forgiven for thinking it was a real person.
The husband and wife designers, who are self-taught, released the latest images of Saya on their Twitter account earlier this week. The animated version of Saya will be displayed at an exhibition in Autumn and the pair, according to Spoon Tamago, are working on a film which Saya will star in.
