Ha! That is a great question!
The old "pat your head and rub your belly" exercise would be the general
idea of a movement-based "tongue twister."
Try to think of signed utterances wherein students just can't seem to get
the movement "right." And then string some of those together.
Something along the lines of: "I exchanged my scarf and tied my shoes."
Another activity that is somewhat analogous to "tongue twisting" would be
exercises like fingerspelling CAT on one hand and COW on the other hand at
the same time, and then switching.
