I have seen it before - pretty cool!

I've never seen one....does it off more information than the charts in Alissa's book?

Not only seen it, had one many moons ago ~ or something like it.

Not sure; don't have one.

I've seen those. Now that I understand them a little, it is one of those things I "must have."
