Saturday

"...During the series of Saturdays, I also recorded the sounds of my neighborhood – the women singing out their windows to their radios, the young men in their low rider cars circling the block, the children, the ice cream carts, etc. These are the sounds that are mixed in the piece. And, these are the sounds that literally drip from participant’s fingertips in Saturday. 
Saturday is presented in the form of an interactive glove. In order to hear the audio, participants magically just press their fingertips to their forehead and they hear the sound without the use of their ears. The glove is outfitted with leading edge audio electronic devices called “bone transducers” which make this possible. These transducers transmit sound in a very unusual fashion. They translate sound into vibration patterns which resonate through bone." - Sabrina Raaf   http://www.raaf.org/projects.php?pcat=2&proj=10#

Grower

"... It hugs the room’s walls and responds to the carbon dioxide levels in the air by actually drawing varying heights of ‘grass’ on the walls in green ink. The Grower robot senses the carbon dioxide (CO2) level in the air via a small digital CO2 sensor. This sensor is mounted high on a wall of the exhibition space and sends data wirelessly to the robot. The number of people in an exhibit space breathing in oxygen and exhaling CO2 has an immediate effect on the sensor. My robot takes a reading of the CO2 level every few seconds and in response it draws a vertical line in green ink on the wall." - Sabrina Raaf http://www.raaf.org/projects.php?pcat=2&proj=4
