If working on this at HackDavis, we'd probably need to

• Set up the project/camera to work with OpenCV
• Use OpenCV to detect faces
• Figure out how to upload a collection of faces to your phone (probably just --> filesystem)
• Implement identification
• Figure out how to save attendance as CSV file / upload to computer
• Design (logo, mockups, artwork for mockups, overall layout and all stylistic choices) = Sarah
• Nice interface for switching between activities / screens (alternatively, nice menu interface)
• Figure out a decent format for camera overlay text
• Optimize everything; this needs to be fast
