If you're really that curious, DynaBlocks (and unofficially GoBlocks as seen in the browser "GoBlocks - Microsoft Internet Explorer") was confirmed by David Baszucki during the 2013 BLOXcon. Keep in mind he says it's a mock-up. Definition of "mock-up" in this case: a working sample (as of a magazine) for reviewing format, layout, or content. (from Merriam-Webster).

This just most likely means they wanted to include many, many ideas they had on the home page of the DynaBlocks mock-up. This doesn't necessarily mean that this is what the website of DynaBlocks ultimately resulted in, since the archives of the website are much different than in the mock-up.
