  We show that there exist constants $\alpha,\epsilon>0$ such that for every
positive integer $n$ there is a continuous odd function $f:S^m\to S^n$, with
$m\geq \alpha n$, such that the $\epsilon$-expansion of the image of $f$ does
not contain a great circle. We also show how this result is connected to a
conjecture of Vitali Milman about well-complemented almost Euclidean subspaces
of spaces uniformly isomorphic to $\ell_2^n$.
