Displaying images using ping pong balls as pixels – “The whole installation exsists out of 2 units. The first is the display-unit, the other one is the cabinet where we store, sort and dispense the balls. The Display-unit is about 2 by 3 meters, The produced picture is aprox. 2,40 mtrs by 1,80! One pixel is 38mm. Each image is built out of 2700 tennistable balls in 6 greytones! Depending on how fast we can fine tune the system, a picture will be fully visible within 2.5 hours.” [via] – Link.
