When reading your piece I formulated this theory in my mind: There is the object, the subject and the environment who all play a role in the meaning of a piece of art when looking at it. If one of these changes, the meaning changes. When I see a painting on a calm white wall in a museum for instance, it somehow mediates something different to me than when it hangs in a more chaotic environment such as a cafe. I can imagine that the advantage of digital art is that it can follow you with use of a smart contract and via the Internet of things, popping up where ever you do or do not expect it. Possibly generating different meanings over time, giving more possibility of reflection by the subject. The value of digital art? Enormous! Perhaps I should write an article about it ;)
Interesting theory, and it absolutely makes sense! I think digital art, when based on smart contracts has a number of advantages. Like you say, one can take it around easily. Like having a library of books in your smart phone or tablet. At the same time, artists get adequately compensated for making their works available on the web.
Curious of where this will take us and what meanings will be generated further down the road..
