Talk to the plants
The Big Brother online takes an unusual shape in the Heinz Ketchup action launched in Sweden. Talk to the Plant is an online experiment where users are encourage to talk to two tomatos plants to prove if a tomato plant grows better with human interaction.
The project is quite original and weird enough to get some attention, but in my opinions lacks in capability to make people come back and spread the word.
The interactivity is probably too poor and there is also an incredible contradiction in the “humanity” of the interaction as messages are not sent using the computer’s mic, but are simply reproduced with a computer-synthesized voice.
