47        - thickness and angle scaling
48        - thinking about the experiment tasks
49            - How to highlight nodes? Draw a ring as in cgoban?
50              Change the color and interpolate to the middle of the connection?
51              Should the connector between two highlighted nodes become
52              highlighted?
53            - Is a static graph (compiled in a displaylist) enough?
54              It can still be rotated.

56    2003-07-07 - 2003-07-08:
57        - thought about surface tension and 3D area--volume optimization
58            - Mean curvature multiplied by surface tension is proportional
59              to the pressure difference (Laplace-Young equation).
60            - Pareto-optimal points of area--volume optimization problems
61              have constant mean curvature, which is analogous to the
62              constant curvature solutions of the 2D length--area optimization.
63            - The only constant curvature surfaces of revolution are
64              catenoid (roulette of a parabola), unduloid (roulette of an ellipse),
65              and nodoid (roulette of a hyperbola, not embedded).
66              Plane, cylinder, and sphere are special cases of the above.
67            - The shape of a droplet is the result of downward linearly increasing
68              mean curvature (as the pressure builds up).
69            - The mean curvature of the (stretched)circuloidal fillet jumps
70              down as it leaves the spherical node (mean curvature 1/radius)  
71              and then increases to the maximum (approx. 0.5/thickness) at the
72              middle of the connection.
