Which LEGO boxes are compatible? TLG has produced a number of sets which come in reusable plastic boxes. I'm curious to know which of these are able to be easily stored together. Primarily, I'm wondering which boxes can be stacked, but if there are any that are compatible in other ways, that would be interesting, too.

As an example, these two boxes can be stacked on top of one another:




There are other variations, even in production currently, which aren't compatible with this style. For example:



I'd like to know which boxes are compatible with others.
There has been a staggering amount of different size and shape LEGO buckets, tubs and boxes. A lot of them are stackable with each other (meaning the same size and shape box produced at the same time can be stacked). I think narowing down the question would be helpful. Are you looking for LEGO boxes currently in production? Or all boxes LEGO ever produced? I just did a quick search on Bricklink and over 300 results came up just for LEGO buckets (similar to the ones you are picturing above): http://www.bricklink.com/catalogList.asp?pg=1&amp;q=bucket&amp;catLike=W It would be huge work to try to work out the compatibility of all of them.
