You don't think a LEGO set of a machine that produces LEGO bricks is meta? I'd have to disagree with you. The truck (3221) isn't even the only one
, though I think it may be the first to come with bricks made up to resemble boxes of LEGO.
As far as the scale issue, I guess you could add this guy
, though I guess in going the other direction, that's more "mesa."
Not to split hairs...reproducing the modular building series in a smaller scale is a bit unusual, just not entirely unique. If all you mean by "meta" is self-referential, though, I'd say these all qualify.
