As it is about to be extinct in the 1st patch I think the Kraken Drive deserves a monument, it was present in the KSP1 for a long time and somehow find its way into KSP2
... and it was FUN
It can be around KSP Space Center or hidden somewhere into another planet/mon in another solar system... like and lost culture thing (as it was surely the ksp1 players that explore ksp2 bug)... an Easter egg kind of thing.
There can also be a contest so the community make this monument to earn a Michelangelo kerbal patch.
I did this and Valentina volunteer for the photoshoot.
PS: no kerbal was hurt during the photo session.
