Félicie [one of my professor] made me discover Dino Pet. This is a toy with living bioluminescent plankton. The owner of the pet needs to feed the plankton in order to keep it alive. It creates a tangible link between the two entities. Reminds me of a part of my dissertation where I quote John Maeda speaking about the ‘digital animism’ we are able to have sometimes (with the tamagotchis for example).
