Their website appears to be a fork of https://github.com/Polymer/docs with just some content changed and the "antha" repo itself appears to be a thin fork of go-lang. Compare:

- https://github.com/antha-lang/antha/blob/master/ast/ast.go

- https://code.google.com/p/go/source/browse/src/go/ast/ast.go

...and the antha code as-is doesn't really do anything? (other than be mostly go)

Not really sure what to make of that.
