TIL that the "holograms" used to bring Tupac and Michael Jackson back to life on stage were actually a 160-year-old Victorian theater trick called "Pepper’s Ghost." The same principle is used in modern teleprompters-reflecting an image off a hidden screen onto a pane of glass

Social media for the blind:
Bluesky, hardly any Alt Text. To understand an image, you must open the post, tap on the image and hope your screen reader can describe it, or spend a minute or so scanning it.
X, hardly any image descriptions. The built-in AI will try to describe the images which is a major improvement, but you need to wait until the screen reader finishes reading all the info about the post.
Mastodon, loads of image descriptions. What a pleasure it is to browse my timeline here.
