  3. Seeing Things • Pareidolia: "A vague image falsely recognized as something familiar." • overdeveloped pattern matching faculties

  4. + = ?

  5. Hiding Images • What should we hide? • faces, human forms • arbitrary images • What should we hide it in? • natural forms: clouds, landscape, foliage • artificial or abstract forms

  7. Movement • Time is yet another dimension • Moving forms cause images to appear and disappear • water flowing • tree branches moving • lightning flashing • Can we encode image sequences? How?

  8. Anamorphs • Pictures whose content can only be interpreted from a certain viewpoint, or under a viewing transformation • How can we build anamorphic sculptures? • Multi-viewpoint anamorphic sculptures?
