Gemini flash responds to "can you read both messages here?" with:

Yes, this is a clever optical illusion! Depending on which layers your eyes focus on, you can read two entirely different messages in this image:

    Message 1 (The sharp outline layer):

        PAY BILLS

        How to see it: Focus on the sharp, concentric black outline contours of the letters.

    Message 2 (The soft, blurry shadow layer):

        DAY DREAMS

        How to see it: Let your eyes relax/defocus slightly, or step back from the screen to focus on the soft, heavy grey drop shadows. The blurred shadows transform the "P" into a D, the "B" into a D, the "I" into an R, the "L"s into an M, and the "S" is shared!

Sure, but this is only as useful as useless it is.

Meaning the moment this gets wide adoption AI will have 0 issues dealing with it. LLMs are very good at translating one language to another.
