Also nice tip: You can click on the image and it will flip it for you. Especially useful if viewing on a computer, and also because some of them mirror instead of flip.
Maybe you would like this one: https://ambigr.am/post/sun--moon-poems
It's the longest ambigram in the world, 2 poems. You read the first poem then turn it over and read the second!
I don't really get this one: https://ambigr.am/contest/sayings. The "up" is supposed to turn to "do" but I don't recognize neither the "d" nor the "o".
Took me a moment too - it's a capital 'D', at about the same angle as the second 'm'. The 'O' just has an extraneous line through it (which was the stem of the P).
The winner of this: https://ambigr.am/contest/sayings
