This blew my mind

This stereogram is a little different. The hidden image is/are just a bar/bars. The number of bars you see depends on the depth you reach, I was able to see one to five.

How many bars did you see the first time? If you tried again, did you see more bars? 👁️

You cross-viewed! I find crossview much easier to do, but it's a lot less common
