Depending on the strength of the exhalation, the user’s distorted
face is reflected on the screen opposite them, so that the user
has to continue blowing in order for the image to remain there.
If they do not, it gradually fades away. The webcam capture is processed;
therefore what is seen on the screen is not what the camera captures.
It is not a “realistic” image as Processing distorts
the picture, breaking it up into a matrix of vertical and horizontal
elements which, seen as a whole, portray a subtle hint of the user’s
face. The black and white image plays with the light intensity in
relation to the strength of the exhalation, allowing each individual
to control the elements that make up the matrix.
