https://imgur.com/a/VsAAN contains an assortment of old images scraped from the IRC logs and my and RobotCaleb's imgur accounts.
These are presented in an arbitrary order and without any specific comment (the dates and other metadata have been lost to time), but still give an interesting and fun view of old development, bugs, experiments, and features that were never finished.
Most of the images are from 2010 ~ 2015.
