the triangle play arrow is frequently used as a next page arrow as well, and noone expects pages to advance automatically instead of just going to the next page when clicking it
Yup. Thank you. It is playing 1 step, so play is right icon for it. I've found a movie/reel play icon that is perfect for the play all should I find a way to fix the timing issue on > than few step folds.
Play for playing all steps in succession.
Pause for pausing play.
Next track for next step in the folding.
Its the most logical. You should see each step as a new track and the whole origami object as an album.
No need for other icons
