Gource visualization of ruby (https://github.com/ruby/ruby) [08-29-2019]. The Ruby Programming Language [mirror]
This visualization is broken, see this one instead: https://youtu.be/dJDriCmPmT4

I made this unlisted and will delete it once people have transitioned links to the updated/fixed version.

This visualization was generated with the following command:
gource \
--path path/to/repo \
--seconds-per-day 1 \
--title "ruby" \
--date-format "%F" \
-1280x720 \
--file-idle-time 0 \
--auto-skip-seconds 0.75 \
--multi-sampling \
