I've finally reached v2.0_pre (aka, "slidey-timey-wimey") of the Gentoo Galaxy Visualization.  I've taken into account a number of issues:

• A slider to go across time very quickly
• The ability to go forwards or backwards arbitrarily through time
• The "year" labels are separately clickable from the streamgraph display itself.
  
• Highlight a dev with the url parameter: ?dev=YOURNICK
• The timey-wimey streamgraph shows the specified developer's activity during their tenure:
  
• The dark purple == commits
• The lighter purple == bugs
• The timey-wimey will automatically jump to the first appearance and play the animation until the dev's last appearance in the timeline.
• The stop button pauses the animation. Toggling the stop button after that will show toggle between:
• Full historical context of the current month (includes inactive and retired developers)
  
• Only active people in the current month

As always, this is a work in progress.  I'd love any and all feedback to help improve this display.  Before 2.0 final:

• More information (including legends and tooltips) about the developer-specific streamgraph
• Bug fixes as they come up
• Feature requests (tweaky/adjusty ones)

I love seeing everyone's different shapes and patterns.   I hope you enjoy it too.

Cheers,
