It's great to see how an artists work can be re-discovered through the internet. Take for example this one: Sound Looking by Kim Kichul. I wasn't there at the exhibition, but since it was uploaded to YouTube yesterday, it's again presented to a large audience, even though it would have been more impressive when seen live.
Sound Looking creates another visible representation of sound, but other than Cylinder, it shows us what happens in real time in stead of a static snapshot. We all know sound is basically moving air, but it's quite fascinating to see what really happens!
