假设您走进都柏林的一个美术馆，看到了您的脸，3D用全彩纸印刷，靠在墙上，茫然地看着您。您所经历的不可思议的感觉肯定会伴随着“什么……？”的问题。在您发生的情况下，您可能无意中成为了希瑟·杜威·哈格堡的展览名为Stranger Visionsat theScience Gallery。
What’s happened here, how Dewey-Hagborg got ahold of your face, is that the artist, who often merges art and technology in ways that raise ontological questions, found a cigarette butt with your DNA on it laying in some gutter in Dublin somewhere. Using聚合酶链反应（PCR）检查了包含的DNA的特定部分单核苷酸多态性(SNP). SNPs are linked to traits that differ among individuals, witha growing library of SNPscorrelated with specific genetic expressions.Rs333例如，与抵抗艾滋病病毒。杜威 - 哈格堡随后扎根alleleson those SNPs that correspond to physically expressed traits and used them to generate a face representing those characteristics, with her own software. Finally, an Mcor Iris printed the model in full-colour 3D. Oh, and some nails or what-have-you hung them up on a wall.
If you really did see your face in this gallery, there was probably also a lot of chance involved. Dewey-Hagborg’s 3D models can’t capture exact replicas of the DNA’s owners. ur DNA sequencing just hasn’t quite gotten to that level of detail, yet. Instead, the alleles that she was able to draw from were a bit more generic: “gender, ancestry, eye colour, hair colour, freckles, lighter or darker skin, and certain facial features like nose width and distance between eyes,”艺术家说。这些参数使她能够产生通常与DNA样本所有者相似的面孔，但这并不十分确切，说：
他们将具有类似的特征和祖先，但看起来可能更像是表弟，而不是人自己的吐痰形象。其原因是多重的，但主要原因是关于面部形态的研究，人的面孔不同，仍处于很早的阶段。许多信息来自所谓的genome-wide association studies，研究了数百或数千种基因组并试图找到相关性的研究。因此，从逻辑上讲，我们序列的基因组越多，我们将发现的相关性越多。我认为我们会接近，但您无法在环境表达中发挥作用。
因此，在艺术家的情况下做过recreate your face, you either look very vague and non-descript or Dewey-Hagborg got very lucky.
The exhibition is meant only as a thought experiment about the possibilities of DNA sequencing technology. Referencing a hair she noticed embedded in a piece of framed artwork at her psychiatrist’s office,Dewey-Hagborg says,
当我看到那头头发并且无法停止思考时，我意识到没有什么可以阻止我分析它的。即使我们通过了法规，我们的人体根本不是旨在避免放弃证据。（尽管我的下一个项目很可能会尝试解决这个问题！
So what I want to do is open a dialogue. I wouldn’t be so bold as to state that I have all the answers but this is real, it is happening now and it isn’t sci-fi anymore. So we need to think about it. We need to deal with it as a culture. Getting a public conversation going is the first step in the process.
Like all technology, DNA sequencing is clearly a double-edged sword. On the one hand, police sketch artists could render DNA samples to create accurate, full-colour, 3D models for investigative and legislative purposes. On the other hand, artists could hang your handsome face up on a wall somewhere and make money without paying you any royalties.
