Pong is an analog recreation of the 70's Atari arcade video game,  
relating the new technologies available for developing artwork and an  
investigation on physical interaction and natural processes. The  
recreation of a lengendary game reflecting today's new media, post- 
digital and diy art creation.

Made by Atari and released in 1972 the Pong game was the first video  
game to achieve widespread popularity in both arcade and home  
console. Since then and more lately history has been giving it full  
credit for having launched the initial boom in the video game  
industry. This game can be seen as the first world known digital  
interactive experience, the artist's idea was to re-build it using a  
different approach and excluding some of the stiff reaction that the  
programming algorithms had, replacing them for physical ones, more  
precisely the use of wind to control a light ball, for example, a  
ping pong ball. For its operation method Andre Goncaves is using  
mechanical hardware instead of being solely a digital piece.

hardware used
In some of his latest projects Goncalves has been using a policy of  
recycling old obsolete hardware, using "dead-media" as the basic  
hardware for developing his projects. For Pong the most important  
parts in the operation method are old A3 printers, taking advantage  
of their mechanical sliding axis system, and replacing the printer  
head with a 12cm computer fan which is being used as the raquet that  
pushes the ball forth.The motors and most of the sensors and switches  
used were also taken from old printers. The arcade machine was bought  
cheap from an arcade games dealer.

Pong is a two-piece installation. The main piece is a self-made  
wooden structure where all the physical action of the game occurs,  
the game area seen on the arcade main monitor through a video camera.  
This structure also hosts all of the electronics behind its working  
method. The other piece is the traditional arcade wooden box with  
attached analog joysticks, buttons, coin dispenser and 2 tv screens,  
one showing the graphics and another with the game view. Both pieces  
are connected through a cable.
The two joysticks will be attached for controling the movement, up  
and down for the left and right motion of the fans, left and right  
for the amount of the wind power blown by the fans.

The game starts after inserting one coin and pressing one button,  
both the score numbers will flash on zero, the ball is released in  
the game and both joysticks activated to let users play the game, the  
scoring is increased as the ball falls off one of the ends of the  
table, replaced on game and carrying on until one player reaches nine  

Pong was supported by the Ernesto de Sousa Fellowship
