fixed mass = 0-47
floating mass = 48-95

even number links link fixed masses to floating ones
odd number links link floating masses to one another in a circle

link 0 = first link from fixed to floaty
link 1 = first link from floaty48 to floaty49
...
link 94 = last link from fixed47 to floaty95
link 95 = last link from floaty95 to floaty48
