In this photo, the bag looks like a black cat from afar. It's kind of hilarious 😆 because I keep thinking one of the black cats are sitting there.

Nine Purple Dots
I posted this little optical illusion yesterday on BlueSky and it proved so popular I thought I’d repeat it here.Whichever of the purple dots you look directly at turns more purple:
I find the effect is stronger on a smaller screen (e.g. on a phone).
In a nutshell, this happens because your eyes have reduced sensitivity to blue light at the centre of your field of view so the purple (which is a mixture of red and blue) changes hue if you look directly at it. For more details see here and the following blog post:
https://www.schulz-hildebrandt.com/9-purple-dots-illusion/
I’m interested to know whether or not this works for people who are colour blind, so if that is you please let me know!

TIL about the Pulfrich effect, whereby lateral motion can be perceived as depth due to timing differences (signal delay) between the eyes.
https://www.youtube.com/watch?v=Q-v4LsbFc5c
The effect can be triggered by wearing sunglasses in such a way that only one eye is covered. 🤪 🕶️
Then you can play "Jim Power: The Lost Dimension in 3D" (SNES, 1993) and the background layer will appear further away (but only when moving).
