Pressible is an online publishing platform developed at Edlab - a research group at Teachers College at Columbia University.
It's a relatively new system (launched formally in June) and has a base of about 110 individual blogs.
I'm interested in visualizing the Pressible 'ecosystem' - and wanted to see in a time-based way how the system as a whole has developed. Using Processing, I created this animation, which shows the system grow over the span of about a year.
Each individual 'cluster' is a blog in the Pressible system. The coloured dots around the clusters are unique posts, which appear in 'real time' as the calendar reaches the day on which they were published.
This animation was built using Processing v.1.2, which is available for free from processing.org
