Andy Garcia's English class at MAHS in Los Angeles used my Black Cloud sensors to study air quality their South Los Angeles neighborhood. Their classroom, p72, was the most polluted site. Worse than a Dry Cleaning business and a gas station, the classroom suffered from overcrowding, poor ventilation and heavy use of cleaning agents. The students brought plants in, and they now study with the doors open.

Greg Niemeyer's blog has stories about modifications he observed while placing Black Cloud sensors around the world.

• Uncountable Things, Berkeley
• Cooking with Gas (Berkeley)
• The right time to air out your home (Oakland)
• Habit and Information (Los Angeles)
• Regeneration (Los Angeles)
• No Sensing Zone (Moscow, Cairo)
