[rob myers] created a dynamic web page that changes based on the colours in his studio. Rob takes a picture of his studio with a webcam, processes the image with Python, and uploads the colour data to a ThingSpeak channel. The web page uses jQuery to access the ThingSpeak API and dynamically update his web page inspired by the colors.
We love the combination of storing data in a channel and using the API to update a webpage dynamically based on the current “mood” of an area. We also love the idea of using a webcam as a passive sensor since almost everybody has one.

I created a chart application to detect the amount of ambient light each day. I used the image from a cam and for each image I ran through the pixels, line by line, and averaged the luminance of all the pixels. The images were taken every minute, so I could develop a daily chart of the amount of light within the cameras view. Didn’t have access to a simple ambient light sensor, but this worked quite well.
I am intrigued by the possibility of re-appropriating data to understand some unintended perspective.
Interesting recent book from O’Reily:
