Last year one of my monthly projects was learning British Sign Language, which was really a lot of fun, very insightful whilst still being challenging, and something I want to dive into more. I stumbled across this article a while back, that discusses the evolution of language generally but more specifically how sign languages change with the times. I found it a really interesting read. Sign language is, obviously, a completely visual medium and that means many of the individual signs reflect the subject in hand.
