Here's a pie chart representation of the time distribution.

CCK

· Posted 4 fixes: latest version is 3.17.13

· Refactored voltage calculations to use new physics engine

· Refactored circuit model to use Java 1.5 features

· resolving #1737: Open switches give incorrect voltage (with JB)

· resolved #1736: Initial window size too large

· Need to decide on disjoint component voltage behavior; should it read 0.0V, ?? or -- or something else? Or we could choose a common ground (as is done in the physics engine).

· We'll still need to decide whether to halt the voltage calculation graph traversal for uncharged capacitors as we did for open switches.

· More testing (with Sam M)

Radioactive Dating Game

· Added object menu titles (with JB)

· Added pixel-hit detection to probe (with JB)

· Added sound (with JB)

Force Law Lab

· Posted 12 minor fixes and revisions, latest version is 0.01.12

· Anything else before interviews?

Misc

· resolved NumberFormatting problems in Moving Man/ar, see #1708 (with JB)

· work with MD to set up subversion/PBG

Upcoming Work

· Force Law Lab (anything else before interviews?)

· CCK

1. Extensive testing (with Sam M)

2. Performance analysis/set time step

· Ramp Simulation, mainly including charts

· JMonkeyEngine/Xith /3dzzd/Flash/Papervision3d/Feng Gui

· Work on website samples with Jonathan, including wicket
