In summary: nothing groundbreaking; everything in here is known anyways.

Eye Gestures

In GlassGestureService, the service detecting winks, there's this enum:

Transitland Frequency Visualization

Accompanies blog post: Transit dimensions: Transitland Schedule API

The frequency.py script:

• Fetches all trips on a given date, between a start time and end time, inside of a bounding box
• Calculates the number of connections between every stop
• Uses a colormap and line width to show more frequent service
• Outputs a GeoJSON map as output.geojson
