I found this somewhere online but I cannot remember where, so reposting here. Using the command line tool 'imagesnap' it grabs a photo every time you make a commit. It is activated through the post-commit hook. ➜ myrepo git:(master) cat .git/hooks/post-commit

gistfile1.rb

#!/usr/bin/env ruby
file="~/.gitshots/#{Time.now.to_i}.jpg"
unless File.directory?(File.expand_path("../../rebase-merge", __FILE__))
  puts "Taking capture into #{file}!"
  system "imagesnap -q -w 3 #{file} &"
end
exit 0
