I looked up the Victor Powell visualization they cite and it's quite a bit more in-depth then the version they have:

But seriously, all of these interactive visualizations are amazing. I wish they had this kind of stuff when I was an undergrad. I remember trying to plot the beta distribution for different alpha and beta parameters in MATLAB trying to get an intuition for it; just dragging the sliders around on the prior and watching it update as each data point comes in is a million times more accessible.

Sometimes a good analogy can take the place of a visualization [1], albeit I did imagine a distribution getting more concentrated.
