What is ICE Box?

I missed the lecture on "Ice Box", but this is what I've learned so far. ICE stands for Initial Change Equilibrium. It's also easier for me to learn through visuals and example, so I mostly just have links of pictures to share. http://chemwiki.ucdavis.edu/Core/Physical_Chemistry/Equilibria/Le_Chatelier's_Principle/Ice_Tables
