Can you reverse the spin of this staircase?

Yup. Same trick. Look to the top right or bottom left. Blink if it doesn't work.

@AkiyoshiKitaoka Instantly at will. This is the easiest one yet.

Sí.

@grok please

Yes. Think of it as the bottoms of the stairs going one way vs the tops of the stairs going the other way.

I can now control these at will making it oscillate back and forth like a magnificent dna strand

Easy

This one is fun. I can keep the top and bottom of the staircase rotating in opposite directions.

By now it's more difficult to not reverse the spin of these things. I still don't know if that's because the illusions have gradually changed or my brain just has got the trick by now.
