How this video was created

For the video creation, Gource which is a software version control visualization tool was used: http://code.google.com/p/gource/

# prepare logs:
svn log --verbose --xml > my-project.log
svn-gource.py --filter-dirs my-project.log > my-project-gource.log

RES="1800x1100"

## viz only, you can even mouse-navigate!
gource --title "GRASS GIS" -$RES -s 0.05 --stop-at-end --disable-progress \
       --log-format custom my-project-gource.log

# make film
gource --title "GRASS GIS" -$RES -s 0.05 --stop-at-end --disable-progress \
       --log-format custom my-project-gource.log --output-ppm-stream - | ffmpeg \
