Interacting galaxies exhibit a wide variety of exotic star forming environments that typically are not seen in isolated galaxies. These include beads-on-a-string, hinge clumps, and tidal dwarf galaxies. I will present multi-wavelength images of a set of nearby strongly interacting galaxies, including Hubble Space Telescope and Chandra X-ray images, and will compare with both analytical models and numerical simulations of the interactions. I will discuss the role that caustics (narrow pile-up zones caused by orbit-crowding) and swallowtails (intersecting caustics) play in triggering star formation in these systems.
