DIY Wright used to say, “I’ve been doing a lot of abstract painting lately, extremely abstract. No brush, no paint, no canvas. I just think about it.”

With Mr. Picassohead you can make a Cubist portrait in about 60 seconds. I spent a little longer on this one, pretending to get the composition right, but it’s hard to go wrong with drag-and-drop noses.

Even simpler is the Mondrian Machine — even a dead guy could produce a neoplasticist masterwork if you clicked the mouse for him.

I suppose the masters wouldn’t approve of these pushbutton knockoffs; Picasso seemed to take a dim view of technology in general. “Computers are useless,” he once said. “They can only give you answers.”

Of course, if you have real talent, machines can be a useful tool, too.’s artPad is a lot easier to use than real brushes and paints, and the gallery has some decent abstracts.

The Experts Speak

“The bow is a simple weapon, firearms are very complicated things which get out of order in many ways … a very heavy weapon and tires out soldiers on the march. Whereas also a bowman can let off six aimed shots a minute, a musketeer can discharge but one in two minutes.”

That’s Colonel Sir John Smyth in 1591, advising the British Privy Council to skip muskets and stick with bows.

InfoToday collected a lot of similarly farsighted advice into an online feature, appropriately called OOPS!

Harrison Ford, Call Your Agent exact layout of Air Force One has always been classified, but How Stuff Works has figured it out and rather recklessly published it online.

When they retire the plane in 2010, I’m hoping they put it up on eBay. At 4,000 square feet, it’s twice the size of my house, and my house doesn’t have a pharmacy, an operating table, 85 telephones, 19 televisions, radar jammers, hand-crafted wooden furniture, and flares to confuse heat-seeking missiles.

Also, Air Force One holds 2,000 meals and feeds 100 people at a time, and it can carry 70 passengers halfway around the world without refueling. I think that would be handy on vacations. I can probably fit 10 people in my dining room if we set up an extra card table, but it doesn’t go anywhere.

City Lights

Earth’s city lights, seen by satellite. You can make out major transportation networks: the American interstate highway system, the trans-Siberian railroad, the Nile. 100 years after the invention of electric light, only Antarctica is entirely dark.

Theseus and the Minotaur

Theseus and the Minotaur is a series of Java-based puzzles in which you have to escape a maze without getting mashed by a computerized monster that moves predictably. There are 14 levels, and I can’t get past level 4.

The interesting thing is that the puzzles were designed by a computer, and they’re now being used in AI experiments at the National University of Ireland. So computers are now solving puzzles designed by other computers.
