The most recent transient masterpiece I've encountered happened to be a cappuccino. I kid you not, it was a cappuccino whose taste, temperature and composition, if possible to frame, would be worthy of any museum.
I write code for fun, I program for a living and I do IT work because it has to be done and I'm not guilty yet of creating any masterpieces in my work so I stand free of bias on the subject. I have had the pleasure of seeing other peoples code that, to my eyes, was obviously the work of a master. The funny thing is, that code isn't displayed for all to see and even if it was, few would see it as a master work, few would take the time to understand what makes it great. Therefore, it is my conclusion that the responsibility for enjoying our own masterpieces, whether they be works of art, poems, pies, passionate statements or digital manipulations, rests first with us, the creators. Whether the world at large discovers them, has the ability to see them for what they are, matters not at all.
