COOL SHIT
Inspiring Creation and Creating Inspiration

               Doug McCune
FUCK
SHIT
DAMN
I still love you
MY STORY
March, 2007
               My story


  • picture of me happy
August, 2008
               My story


  • picture of me busy and rich
February, 2009
FUCK FLEX
Flex is a crutch, it's a box. Fuck Flex, leave it
behind. If I'm hitting a brick wall then I need to
find another road. Somewhere there's a path
that leads higher up the mountain instead of
circling at the same altitude. I'm driving faster
and faster, but all that does is get me back to
where I started in less and less time. I'm
repeating myself repeating myself, and in the
process I'm getting dizzy. I'm getting sick. Time
to pull over. Time to get out of the car. I'll walk
up this fucking mountain if that's the only way
to get a different perspective.
I’ll be talking about:

  Steganography
  Head Tracking
  Augmented Reality
This is not a talk about:

  Steganography
  Head Tracking
  Augmented Reality
This is really about:

  Inspiration
  Exploration
  Creation



                        10
STEGANOGRAPHY
WTF is Steganography?

• Wikipedia says: “the art and science of
  writing hidden messages in such a way that
  no-one, apart from the sender and intended
  recipient, suspects the existence of the
  message, a form of security through
  obscurity”
• Doug says: “Straight up CSI shit”
Inspiration
Lee’s Dead Drop

Exploration: File Types
  for Steganography
• Graphics formats: BMP (super easy), PNG
  (kinda easy), GIF (not sure)
• Audio: MP3 (no idea)
• SWF?
• How do you learn? Read the specs, read
  Wikipedia
Exploration:
   Least Significant Bit
• One RGB pixel: #RRGGBB
• Composed of 4 bytes (8 bits each)
• We only modify the last bit of each byte
  (which might mean no modification)
  original bytes              modified bytes

   01010101        01010101    01010100
Exploration:
    Comparing BMP and PNG
             BMP               PNG

  Header     54 bytes   IHDR   N bytes


Raw pixels   0x000000   IDAT   filter byte
             0x00FF00
                               pixels for row 1
             0x00FFFF
             ...
                               filter byte

                               pixels for row 2
Exploration: Open Source
     PNG Libraries

• PNGEncoder - part of the Flex framework
• PNGDecoder - written by Heriet
  (heriet.info)
Creation
STEGAsaurus

• AIR app for embedding and extracting
  secrets from PNG files
• hide secret text messages
• drag and drop files to hide them in an image
Take it to the next level

•   Encrypt a SWF within a PNG and load it at
    runtime as an RSL or a Flex module

•   Encrypt inside mp3s and playback secret message
    with text to voice software (Merapi?)

•   AIR web browser that would show secret
    messages in images while browsing

•   Use TwitPic to tweet secret messages hidden in
    images

                                                      30
HEAD TRACKING
Inspiration:
Johnny Lee




http://johnnylee.net/projects/wii/
Inspiration:
                       Flash Demos



        Boffswana                                      mr. doob
http://www.boffswana.com/news/?p=498   http://mrdoob.com/90/Face_tracking_+_3D_Scene
Exploration:
  Marilena and Deface
• Marilena is written by Masakazu Ohtsuka
 •   part of the Japanses libspark project (which also
     includes FLARToolkit and other badass stuff)

• Deface is written by Steve Shipman
• both are based on OpenCV that uses “Haar
  Cascades” to detect faces
Exploration:
        Haar Cascades
• Converts image to numeric computed values
  (based on surrounding pixel values)
• Scans for known “feature sets” in an image
• Tree-based structure with an array of root
  feature nodes
• Scans over and over at different resolutions
• I think it might be racist
Exploration:
          Haar Cascades
• The algorithm was designed to efficiently
  scan one image once
• NOT designed to continuously scan live
  video
• But with some simple changes we can fix
  that
Creation:
Flash Target Demo
Creation:
Safe Sexting
Head Tracking in Games




  http://www.youtube.com/watch?v=e2ay5jOGI0w
Creation:
Crappy Top Gun Game
Take it to the next level

•   Make some games that don’t suck

•   Multi-player head tracking games using CoCoMo

•   Eigenfaces AS3 implementation

    •   used during login to check identity

    •   restore user’s preferences based on who they are

    •   customize UI based on gender or race ( and
        prepared to get sued)

                                                           50
AUGMENTED REALITY

          http://vimeo.com/3853814
Inspiration:
Weird Dolls from Japan




  http://www.geishatokyo.com/jp/ar-figure/figure.html
Exploration:
          FLARToolkit
• ARToolkit is the base, written in C
• FLARToolkit is a AS3 port (C ported to Java
  ported to AS3)
• http://www.libspark.org/wiki/saqoosha/
  FLARToolKit/en


• WARNING: GPL License
Creation:
           Dress Up


• I apologize in advance for what I am
  about to do
Take it to the next level

• Greeting cards
• Wearable AR clothing
• Dorky graffiti
• Screw Flash, it’s about the iPhone

                                       1:10

  • 26. Inspiration: Flash Demos Boffswana mr. doob http://www.boffswana.com/news/?p=498 http://mrdoob.com/90/Face_tracking_+_3D_Scene
  • 27. Exploration: Marilena and Deface • Marilena is written by Masakazu Ohtsuka • part of the Japanses libspark project (which also includes FLARToolkit and other badass stuff) • Deface is written by Steve Shipman • both are based on OpenCV that uses “Haar Cascades” to detect faces
  • 28. Exploration: Haar Cascades • Converts image to numeric computed values (based on surrounding pixel values) • Scans for known “feature sets” in an image • Tree-based structure with an array of root feature nodes • Scans over and over at different resolutions • I think it might be racist
  • 29. Exploration: Haar Cascades • The algorithm was designed to efficiently scan one image once • NOT designed to continuously scan live video • But with some simple changes we can fix that

  • 34. Take it to the next level • Make some games that don’t suck • Multi-player head tracking games using CoCoMo • Eigenfaces AS3 implementation • used during login to check identity • restore user’s preferences based on who they are • customize UI based on gender or race ( and prepared to get sued) 50
