Energy Skate Park

� Posted 3 revisions, latest is:

http://www.colorado.edu/physics/phet/dev/ec3/1.05.27/

� Added a threshold to prevent tiny bounces

� Added restore point for �return skater� or �bring back��

� Lots of tiny user interface and graphics fixes (see changes.txt linked above)

� Recommend the rest of the team look at this before thorough investigation; also recommend thorough investigation is incremental and collaborative, instead of a large batch operation.

� This simulation is ready for phet-team testing and/or user testing.

� Should I look through Keller�s previous comments for recommendations that still apply?

Slider (new controls implementation)

� Discussion with Chris about new controls design

� Tested new controls

� Converted Energy Skate park to use new controls

Build Process

Piccolo

� Discussed Piccolo 2.0 option with Piccolo authors

� Piccolo team has agreed to sponsor our recommendations

� Piccolo team granted write access to piccolo repository.

Upcoming Work

� Energy Skate Park?

� Rotation (partly with John)

� Improve build system (with John)

1. Rewrite main build script to use java-based build task

2. Generalize JNLP file generation

3. Fix simulations to match build information requirements (directory for localization information, standardization, etc.)
