Portnoy consulted with a team of futurologists, trend forecasters, environmental scientists and agricultural experts to predict what will be the “hot” vegetable 20 years from now. Many considerations were taken into account, such as predictions about the environment, deforestation, developments in genetically modified crops, international trade, etc. Although the Kalochromes appear to be innocuous screen prints of kale, they are actually encrypted images, through the process of steganography, of photographs of the “Kale of 2034”. In steganography, often used by terrorist organizations to pass undetected messages online, any image can be hidden within the digital information of another image. Twenty years from now, the decryption key to the Kalochromes will be provided, so the images of the predicted vegetable can be revealed.
