If you want a new idea of what to get someone for their birthday and you have a big chunk of money sitting around freely then you could get one of these DNA art pictures. It is actual DNA put in to print. To get the image you need to submit a sample from your cheek using a swab kit. You send this sample to a lab and they then create your DNA etched on to crystal or paint it on to canvas.
It costs 415 pounds though, so you need to be a bit generous or posh to buy one of these for a friend or family.
You can pick up the kit from DNA-Artuk. Although its kind of cool to tell your friends about the image and what makes you male and what your blood group is, I dont think I will be forking out 415 for one just yet.
