]]> [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.
