The Kama Sutra has been sexed up for the 21st century with a new app that enables couples to study its erotic poses in 3D.
State-of-the-art technology transforms the historic manual's illustrations into holograms which pop up in front of a smartphone or tablet.
Each image can be seen from all angles meaning users are offered a complete view of the guide's sexual diagrams.
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".
Hazel Cushion, managing director of publisher Xcite Books, said: "For more than two thousand years couples have turned to the Kama Sutra for advice and guidance on how to have a fulfilling love life.
"But some of the more challenging positions like the Prone Tiger, the Catherine Wheel or the Peg have left readers a little baffled. That is until now.
"The Kama Xcitra uses state-of-the-art technology to help couples explore interesting sexual positions whilst having fun in the process.
"Each image appears to pop out of the page as a 3D hologram right in front of the reader's phone.
"The viewer then moves their mobile device around to appreciate the position from all angles. As a result, each position becomes clearer, finally solving the problem of where to put that awkward elbow."
