Rain Dance and Piracema were installations developed for the opening of Espaço Israel Pinheiro, a space dedicated to Development, Justice and Environmental issues in Brasília. Both installations run from the same PC/projector and use a playstation eye camera as sole input.
In the Rain Dance game, you begin with a dry area, where almost all vegetation is gone. When you enter the game a small cloud enters following you. As you begin to move it gets bigger and eventually starts to rain. You must then walk along the screen to direct the rain to the driest areas. As you rain over the earth it will become greener and the trees will begin to sprout and gain green leafs.
Piracema is the name given to the period of the year when fishes swim up rivers, against the current, to breed at the river heads. This a very important for the maintenance of the species and can be hampered by damns or other man made obstacles. In this game you must help the fishes swim upriver by guiding them with your body to avoid liter that has been thrown on the river.
The goal of both games is bring into focus the human role in the changes of natural processes. The games were co-designed with Francisco Marinho and co-developed with Ilusis Interactive Graphics.
