We show how observations of temperature fluctuations in cosmic microwave background (CMB) can be used to extract information related to the large scale structure, including dark matter distribution, pressure and halo velocities involving the line of sight, transverse and rotational components. The frequency spectrum can be used to separate the SZ effect from thermal fluctuations. The measurement of higher order correlations in CMB can be used to extract effects involving lensing and kinetic SZ effects. A high signal-to-noise arcminute scale CMB experiment can be used to construct the weak lensing convergence, which is useful given that the background source, CMB anisotropies at the last scattering surface, is well understood.
