eRiceCooker tracks Internet news about genetically modified rice. Whenever there is a new report about GM rice, a quarter cup of rice is dispensed into the cooker. When the cooker has enough rice for a meal, water is added automatically to the rice and the cooker is switched on. When the rice is done, an email is sent out to inviting people to eat the rice. The more news reports appear, the more rice is cooked, the more often invitations are sent out. The project is designed to create awareness to issues surrounding genetically modified organisms by producing excessive amounts of cooked rice and attempting to feed people with it.
