It's amazing what you can do with a mobile phone these days.
The Kama Sutra, the 2,000-year-old sex manual, has been sexed-up for a 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.
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".
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."
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.
The Kama Sutra is widely considered to be the primary Sanskrit work on human sexuality.
It was first translated into English in 1883 under the guidance of Victorian explorer Richard Burton.
A section of the celebrated text consists of practical advice on sexual intercourse.
