  10. VITA-e Example

  11. Originally [web] search and KM • But the gravity can cluster and group other items. • N.B. the quantized use of the 3rd dimension [height above the floor]

  12. Concepts 3 fixed planes Extracts web pages VITA General Layout Mechanism

  13. Quantized 3rd dimension—say— For a collection of suspect emails about something perhaps quite innocuous. • “To” level • “From” level • Body level Traffic analysis should ID cells of activity Perhaps identify a single text thread

  14. Other possible floorings • Time [datestamp] level • To-from level • Keyword level

  15. Or, network protection • From • To • Sites

  16. Common Fate • Who’s attached most strongly to whom? • Who’s pinging whom? • Who’s pinging many? • Or, who’s being pinged by many?
