The Sleep Blanket

Over a period of three months, Seung Lee knit a blanket showing a visualization of his infant son’s sleep patterns from birth to his first birthday.

The sleep data was collected with the BabyConnect app which lets you export to CSV. The CSVs were filtered and converted into JSON (using Google Apps Script and Python) which could then be used for visualization and tracking.
