Static pictures do this no justice. I've uploaded an mp4 video of the entire software development history of fwts so you can see Gource in action.
To generate the video, the following incantation was used:
gource -s 0.03 --auto-skip-seconds 0.1 --file-idle-time 500 \ --multi-sampling -1280x720 --stop-at-end \ --output-ppm-stream - | ffmpeg -y -r 24 \ -f image2pipe -vcodec ppm -i - -b 2048K fwts.mp4
..kudos to Chris for this rune.
