I don't either, maybe my mathematical maturity is not high enough to be able to work at the level of abstraction that can see a connection between ravens and "vector of hours".

I also played around with the canvas and couldn't draw anything, I tried taking the dot product of a "raven" and a "crow", piping it to a "sun", and didn't see anything. I would have expected something since a raven and crow are similarish so should have a non-zero dot product. But for that matter a dot product of a raven and a raven piped to a sun doesn't show anything either so I'm just completely lost.
