They were neat to loook at but not very impressive in practical terms. So you can take 3 semi-floppy coiled things and turn them into one semi-rigid thing. But only one of them can be attached to something, or the actuator won’t be able to move.

The tent application is the closest one to something practical and the tent was not very rigid, nor was there any real advantage to it over conventional methods.
