-> “Imagini is a London-based software firm founded in 2006. It uses images instead of questions to do marketing tasks such as psychographic marketing research[1] and social networking. Using Imagini's ‘VisualDNA’ technology, Web visitors respond to queries such as ‘My biggest vice is...’ or ‘My idea of love is...’ by clicking on images, and software algorithms analyse the choices made to learn more about that particular person's preferences, likes and attitudes; then, a profile is constructed of the person which the firm describes as that person's Visual DNA.” – [Source](https://en.wikipedia.org/wiki/Imagini)
