Abstract: The purpose of this short note is to illustrate the utility of (semi-) dendroidal objects in describing certain ‘up-to-homotopy’ operads. Specifically, we exhibit a semi-dendroidal space satisfying the Segal condition, whose evaluation at a $k$-corolla is the space of ordered configurations of $k$ points in the $n$-dimensional unit ball.
