For such a fiendishly simple applet, this was very difficult to come up with any
comments.
I like the bidirectionality aspect of the thing; you can take it starting with
either fraction and get to where you need to go (which is how it should be).
This tripped me up, however, as I kept wondering "I just took a half of the red
thing, so why is there leakover blue in the other area? Why do I need that?"
This isn't BAD by any means, but it definitely stymied me until I figured out
that you needed both colors like that for a proper twoway gridding.
I wish there were some way to do this with more than two fractions, but it'd
just be messy in 3D, and more than that would require extreme strangeness.
Can anyone think of a different way to represent this in 2D for more
fractions?
