I greatly enjoyed the white-and-gold-or-blue-and-black dress. (It was blue and black.) If you never checked out the Amazon reviews for that dress, you really ought to take a moment and do that.
However, this post is really about a different illusion.
Can anybody see red and green dots moving downward?
I see only yellowish or greenish dots moving left to right. The red and green ones would be more seasonal, but … nope, can’t manage it.
