This post is a written response for Ken Friedman's piece titled "Mail Art History: The Fluxus Factor" in a magazine published by Franklin Furnace.
Correspondence art has been an important part of the Fluxus movement since the 50s - 60s. It used to rely heavily on postal service to transmit small scale media, thus it has always been famously known as "Mail Art". The type of media that is commonly used include things such as postcards, photo collage, rubber stamps, or anything can be put inside an envelope and sent via post.
What I found the most interesting from the reading is how he talked about how today's new forms of electronic communications blur the edges of the kind on medium taking place in correspondence art or mail art. The main challenge is how we can fit in today's technology into replacing transmission method for sending art instead of using the postal service. In a way, to me this entire thing sounds exactly like the type of solutions that can be done in the domain of "Internet of Things". As the computing resources become incredibly less expensive than it was few decades ago, the technology itself become widely accessible to everyone and especially DIY maker or artists. I think this perfectly adheres the spirit of Fluxus which emphasizes heavily on Do-It-Yourself culture and hack.
