Recently, I was reminded of the videos that have been created in relation to the international linguistics olympiad. I thought I'd do a post with a couple of them.
This year's, 2015, local organisers in Bulgaria made several videos. You can find their channel and all of them here. The longer nice compilation one is here, with plenty of drone material :)!
Last years organisers, 2014, in China also made a very nice compilation video!
I also recommend watching this video by NativLang, who is not officially part of the IOL but who works with linguistics outreach and did a nice video explaining the IOL:
Hope you enjoyed them!
