that makes the width:diameter ratio of a yoyo look greater than usual?
I have no idea what you’re talking about
Then why would you reply to the topic…
Anyways to answer the question, this illusion might be similar, where the height of the arch is comparable to the width of the yoyo whereas the base length is comparable to the yoyo’s diameter
I didn’t give thanks to your post because of your insight of the optical illusion…it was primarily for your first statement! I HAVE to give thanks when one makes me smile. ;D
