I love the graphs - it makes everything so clear, leaves nothing to chance. I'm a language person, and I always did the same thing in any language I learned or taught - charts, charts, charts. And my students loved them... most of them, anyway. So your graphs are the visual equivalents of my charts.
Yes, first I want to try the Northern Star, which has really caught my fancy; then the Carpenter's Star. Unless I just can't control myself and start a block early (I know myself well!), it will be later in the year when I get to them. But get to them I will. :)
