We present a class of spacetime rotations that preserve a proportion of spacetime supersymmetry. We then give the rules for superposing these rotations with various branes to construct rotating brane solutions which preserve exotic fractions of supersymmetry. We also investigate the superposition of rotations with intersecting branes at angles and we find new rotating intersecting branes at angles configurations. We demonstrate this with two examples of such solutions one involving intersecting NS-5-branes on a string at $Sp(2)$ angles superposed with fundamental strings and pp-waves, and the other involving intersecting M-5-branes on a string at $Sp(2)$ angles superposed with membranes and pp-waves. We find that the geometry of some of these solutions near the intersection region of every pair of 5-branes is $AdS_3\times S^3\times S^3\times \bE$ and $AdS_3\times S^3\times S^3\times\bE^2$, respectively. We also present a class of solutions that can be used for null string and M-theory compactifications preserving supersymmetry.
