Let the (subword) complexity of a sequence u=(u"n)"n"="0^~ over a finite set @S be the function m@?P"u(m), where P"u(m) is the number of distinct blocks of length m in u. Let t=(t"n)"n"="0^~ denote the Thue-Morse sequence. In this paper we study the complexity of the sequences t"H=(t"H"("n"))"n"="0^~, when H(n)@?Q[n] is a polynomial with H(N)@?N. In particular, we solve an open problem of Allouche and Shallit regarding (t"n"^"2)"n"="0^~. We also study the vector space over Z/2Z, spanned by the sequences t"H.
