Geneportrait is a perfect fusion of science and art. Art made from your unique DNA, or in other words personalized genetic portraits made from a sample of your saliva.

JL Soto, Founder of Spain based Geneportrait says: "Our genetic portraits create unique fingerprints for every individual (including pets). However, These DNA patterns are anonymous: they hold no medical or legal value. Also, the identities of the individuals in the portrait are anonymous to us (we only require mailing info and consent of a contact person).
We can include multiple individuals in one single portrait which makes the experience much more meaningful: You can directly compare your fingerprint with your loved ones', generating both a unique sense of closeness and individuality." The DNA artwork is delivered on CD. A single DNA signature artwork sells for 190 Euro (~$240)
