Abstract: We define a new $E_{\infty}$ operad based on surfaces with foliations which
contains $E_k$ sub-operads. We construct CW models for these operads and
provide applications of these models by giving actions on Hochschild complexes
-thus making contact with string topology-, by giving explicit cell
representatives for the Dyer-Lashof-Cohen operations for the 2-cubes and by
constructing new $\Omega$ spectra. The underlying novel principle is that we
can trade genus in the surface representation vs. the dimension $k$ of the
little $k$-cubes.
