Oracle is an interactive work created by Fred Murie and Flavien Théry which comes in different formats. A screen displays a pattern of "noise". When the user touches this random pic, it brings out the characters, which merge again as soon as the movement stops. As during a séance, it spells words that would all be addressed by a mysterious entity messages. Thus, from a seemingly empty space, emerge signs of a hypothetical technology beyond.
Don't install this! It's a waist of time. Words make no since at all!
