(Im)possible Baby is a speculative design project that aims to stimulate discussions about the social, cultural, and ethical implications of emerging biotechnologies that could enable same-sex couples to have their own, genetically related children. Delivering a baby from same-sex parents is not a sci-fi dream anymore, due to recent developments in genetics and stem cell research. In this project, the DNA data of a lesbian couple was analyzed using 23andme to simulate and visualize their potential children, and then we created a set of fictional, "what if" future family photos using this information to produce a hardcover album which was presented to the couple as a gift. To achieve more public outreach, we worked with the Japanese national television service, NHK, to create a 30-minute documentary film following the whole process, which aired in October 2015.
