London: The 2,000-year-old sex manual - Kama Sutra, has been sexed-up for the 21st Century audience with a new app that enables couples to study its poses in 3D.
Using state-of-the-art technology the app transforms the historic manual's illustrations into 3D images when viewed through a smartphone or tablet, the Independent reported.
Each image can be seen from all angles meaning users are offered a complete view of the guide's sexual diagrams.
The new app, which it may be best to avoid using on the morning train to work, takes users through sexual positions such as the Catherine Wheel or the Prone Tiger, allowing amorous couples to view the position from a variety of angles.
The free app comes with a new version of the text which is based on ancient Indian Hindu philosophies and is believed to have been written around 2,000 years ago.
The Kama Xcitra promises to help couples master positions set out in the original book and ensure they are brought "closer to the action than ever before".
The app works in conjunction with 69 poses and allows users to customise the appearance of models, changing hair and skin colour as well as adding music as a soundtrack.
