[LIFE6T.BBX 8KB]
Life6T is the same as Life6 with the addition of wrap-around links to make the 6x6 playing field toroidal. This means that Gliders (among other patterns) will circulate forever. For information about Life and how to use it, see the documentation for Life6.
An interesting property of Life6T's toroidal nature is that the left-most or right-most column of 'pixels' can be dragged to the opposite side, and the resulting pattern will be identical. The same applies for moving rows from the top to the bottom or vice-versa.
