Agreed. I'd probably reverse Hexstream's comment in that I find it much harder to think up good ideas than actually implementing them.
It just never would have occurred to me to use Emacs as a video editor (my brain has been conditioned to think of it strictly as a text editor). If that idea had popped in my head then implementing it, relatively speaking, would probably have been less of a challenge than coming up with the actual idea in the first place which requires overcoming my preconceived notions.
In this instance, the idea is far more impressive than the actual code. This demonstrates innovation beyond technical prowess because it added a new way of doing something to a familiar software tool that most people would never have thought of.
