Printing Facebook mugshots for a party.

instructions.md

Using the Facebook Graph Explorer, perform this query. Make sure you have permissions to access users' photos. {event-id}/invited?fields=picture

Grab the JSON that results, and copy/past the array under the "data" attribute to attendees.json

In Ruby,

require 'json'

filename = 'attendees.json'
json_string = File.open(filename, 'rb') { |f| f.read }
attendees = JSON.parse(json_string)
attendees.select { |i| i["rsvp_status"] == "attending" }
         .map {|i| i["picture"]["data"]["url"]}
         .map {|url| url.gsub("_q","_n")}
         .each {|url| `curl -O #{url}`}

Then use iPhoto or similar to print out contact sheets.
