How about this for an emblem? It looks great on the FROG polos.

The emblem printed on the polos is actually a reversed version of the docking target. It is a set of ArUco markers that just happen to say FROG – though it probably took Fernando Caballero quite some time to find them.  UPO uses this ArUco marker to align the FROG to its charger during the docking procedure.
