I can split my writing to right and left in script at same time. It is much easier than I would expect. Been trying it with the Stardust in my minds as I mouth the words . Not sure it is doing anything but I am trying to see the left and right words going in opposite directions (to the left in mirror orientation). It feels like it defines the left tongue slightly more..
Not sure. It is slightly humorous in the fact that I can barely talk or write in one direction
