I'd assume that all galaxy groups are Gravitationally bound, and when looking at the group you're in, the galaxies would appear to be closing, while the other groups would appear to be opening; this is an effect of Hubble's law, everything is moving away from any observer at 67.80±0.77 (km/s)/ Mpc, thus the farther away, the faster it is going away no matter where you are . Even at that, I've seen several Hubble images showing galaxies colliding just like we're about to do with Andromeda.
