Lazy Composting with a Bin

I attended a very interesting Saturday seminar a few weeks ago, held at the City / County (?) facility on Coors. A gentleman - whose name I did not get and was not on the card he passed out - gave a very informative talk on composting. As I am very lazy, the "cold composting" technique caught my attention. His presentation included a picture of a plastic-type, pre-made container in which you "put in at the top, and many months later, take out from the bottom" (my kind of composting!). I wonder if the manufacturer of that composting bin could be obtained from the speaker? I have googled and seen bins somewhat similar, but nothing looked identical to what the slide showed. Thank you for your help and I look forward to hearing the results of your "detective work"!
