In reading David Oreilly's article "Basic Animation Aesthetics" I found myself wondering a few things about what the things he said:

He talks about how his use of simplicity in his short "Please Say Something" created a visual coherence. Can simplicity hinder coherence, or is it always beneficial?

He states that "The technology of 3d animation is developing at a blinding speed, new tools and
techniques are being added every year, and it is only a few films which survive this
development and manage to appear undated." What is it about these films that presents them from aging?
