Academically interested, yes. Have time for; hell no! I can barely keep up with developing and scanning the photos I take on film that I don't need to manufacture myself, and I'm waaaay behind on printing. Adding another very-time-consuming process step is just not going to happen, especially when it's not going to get me quality anywhere near as good as commercial film stocks.
I do quite enjoy reading the threads about it that pop up here occasionally though.
Probably one day I will try carbon printing to see what the relief looks like, but that's probably about the limit for me smearing goop on stuff.
