Tor.com has republished a great chart from Bad for You: Exposing the War on Fun!, forthcoming in on January 7. The chart details the central thesis of the book: that "the long-standing campaign against fun" is a recurring story in which anxious, killjoy grownups make up stupid explanations for why the stuff their kids like is terrible and should be banned, and the golden era of their own childhoods (and the amusements that reigned then) should be restored.
The chart starts with Trithemius's 1494 rant against printing presses ("The word written on parchment will last a thousand years. The printed word is on paper. How long will it last?") and moves smartly through books, steam engines, newspapers, photos, telegraphs, movies, phones, phonographs, radio, TV, computers, and (of course), the Internet.

Cover the middle seam with your finger, marvel as the contrast effect changes EVERYTHING. Jason Kottke thinks the creator is a witch. When I showed it to my daughter, she said, "Well, your finger is covering up the light that's making it brighter," which is true in a weird sorta way.
Pneumatic tube systems — little canisters shot through a series of tubes via the power of compressed air — have been around since the 19th century when they were briefly popular as a way to quickly deliver mail in big cities. Today, they're probably most familiar from their use in drive-through banking, but the tubes also turn up at libraries (the one at the main branch of the New York Public Library is particularly steampunky), in scientific laboratories, and in hospitals.
Last month, I spent an inordinate amount of time in one Minneapolis area hospital, waiting for an induced labor to kick in. How do you entertain yourself between the insertion of the IV line and the beginning of serious contractions? Turns out, you go on a lot of short walks, you watch some TV, and (if you're lucky) you convince the nurses to let your husband "mail" his cell phone from the labor/delivery department to the post-natal department, using the hospital's pneumatic tube system.

This is a picture of a wave crashing on the New Jersey shore. It glows because of dinoflagellates — little, single-celled plants, animals, and bacteria that float around on the water, moving about with the help of long, moveable protein strands called flagella. Some dinoflagellates are bioluminescent; that is, chemical reactions inside their bodies produce light. The result is glowing oceans. Or, as maker Caleb Kraft recently discovered, the dinoflagellates also make for a soft blue nightlight with really nifty special effects.
You can watch Kraft's nightlight project at YouTube. It's pretty simple to do at home. At it's most basic, all you need to do is purchase some bioluminescent dinoflagellates online, keep them alive in your home, and give them a good shaking occasionally to trigger the chemical reaction.
