From Montreal Tech Watch:
The Open Source Android App is called “Portable Microbiology Lab” and here is how it works:
A user puts a water sample on a 3M petrifilm and tells the App to register GPS coordinates of where the water was taken. After a 24 hour incubation period, the user photographs the petrifilm….
…The App then applies filters to the image and counts the bacterial colonies. Sophisticated image recognition shows if the bacteria is ”e.coli” (very bad), “total coliform” (bad), or environmental bacteria (not so bad): this is done by analyzing by the color and nearby bubbles.

20 Hz observes a geo-magnetic storm occurring in the Earth’s upper atmosphere. Working with data collected from the CARISMA radio array and interpreted as audio, we hear tweeting and rumbles caused by incoming solar wind, captured at the frequency of 20 Hertz. Generated directly by the sound, tangible and sculptural forms emerge suggestive of scientific visualisations. As different frequencies interact both visually and aurally, complex patterns emerge to create interference phenomena that probe the limits of our perception.
