  2. Tactical Audio for Surgical Navigation Patent application filed.
  3. Latex2html versions of main DMT LaTeX documents.
  4. Much new word7 material html-ified and published.
  5. SpiderWeb algorithm approved for patent after appeal.
  6. Tactical Audio for Neurosurgery Navigation sister project IRB approved.

Theoretical Accomplishments
Non traditional criticalities, i.e., frilly edges surrounding a plateau.
Pales added to Peaks, Pits, and Passes.
Feature space hierarchy.
New theoretical collaborators. Historial References to Topologic Surgery from Wall(1960's).
Literature search and anecdotes. 
Programming Accomplishments
New Daughter of SpiderWeb software launched.
A multithreaded parallel implementation to build Morse Criticalities Graphs.
X Interclient Synchronization:
How to send X-Events to processes sharing an arena:

"This application, contributed
by long-time DT-supporter-and-consumer Dr. Dan Karron, demonstrates how to use shared memory and X
 events to synchronize multiple X processes. "
Published by the Silicon Graphics Developer's organization on their Developers Library.

X-Windows overlays and usual visuals demonstration code for use with software.

Shared Memory Tcl/Tk interface prototyped and in alpha use. 

Milestone Objectives Achieved.
Programming effort launched.
Shared Memory Programming model implemented.
Tcl/Tk GUI development started.
Rapid contouring display completed.
DMT graph window development started. 
Publications
DMT paper re-submited with many editorial and didactic changes and additions.
NEEDS TO BE DONE
Demonstration of contouring errors in 2d.

Start Criticality Graph window.

Image registration window from Criticality graph. 

WOULD BE COOL TO DO
3d contouring errors.

Consistency checks on contour partitions of space. Accumulate area under each contour
by Green's/Stokes theorem. All area/volume should be accounted for. Hard to spot errors can be found.
