Link to Escher's Droste Print Gallery on Flickr, Link to Droste Effect TutorialThe 'Droste effect' is a Dutch term for a specific kind of recursive picture, one that in heraldry is termed mise en abyme. An image exhibiting the Droste effect depicts a smaller version of itself in a place where a similar picture would realistically be expected to appear. This smaller version then depicts an even smaller version of itself in the same place, and so on. Only in theory could this go on forever, but practically it continues only as long as the resolution of the picture allows, which is relatively short, since each iteration exponentially reduces the picture's size.
The term was coined by the poet and columnist Nico Scheepmaker at the end of the 1970s. It is named after Droste, a Dutch brand of cocoa, whose box has a picture of a nurse carrying a serving tray with a cup of hot chocolate and a box of the same brand of cocoa.

Charles Ferguson made the Iraq documentary No End in Sight with money he earned when he sold his startup company to Microsoft. Snip from Joe Garofoli's feature in the San Francisco Chronicle about Ferguson's film (distributed by Magnolia Pictures), his message about Iraq, and the start of his new career:
In 1996, Charles Ferguson sold the startup company he founded to Microsoft for $133 million. He was 41, had $14 million worth of growing Microsoft stock in his pocket after paying off investors - and was thoroughly exhausted after barely sleeping the previous year. Then for the next eight years, he wrestled with the question that relatively young entrepreneurs rarely consider until they hit it big:Link to SFGate article. Link to No End in Sight website. The movie is playing in some cities now, and opening in more around the US throughout this month. (Thanks, Wayne Correia)Now what do I do?
"For quite a while I didn't know," said Ferguson, as he looked out a window of the book-filled two-bedroom Berkeley home near Strawberry Canyon where he has lived since before he struck gold. While he was hardly idle during that time - he wrote two books, including the scathing "High Stakes, No Prisoners" (1999) about his startup experience, traveled and served at the Brookings Institution think tank - he felt unfulfilled. He couldn't sleep, and felt himself growing too dependent on sleeping pills that left him feeling dopey. And for a man who thinks at warp speed, that wouldn't do.
A little more than two years ago, Ferguson said he started to "get my energy back." What germinated during his hibernation was "No End in Sight," a documentary about how the United States has botched the occupation of Iraq. It opens Friday in the Bay Area after winning the special jury prize for a documentary at the Sundance Film Festival this year and garnering largely rave reviews in New York, where it opened last month.

The president of Students for a Free Tibet is in Beijing right now, exactly one year ahead of the 2008 Olympics, vlogging and blogging about Tibetan sovereignty and being a general pain in the ass to the Chinese government.
Lhadon Tethong's liveblogging experiment is incredibly ballsy or incredibly foolhardy, depending on how you look at it -- hard to imagine this lasting long before authorities arrest, extradite, or take some other action to stop the activity.
Apparently, she's already attracted a group of official government "escorts".
Incidentally, Ms. Tethong's uncle is the most senior advisor to H.H. the Dalai Lama.

365gay has more on what happened:
Titusville Officer Danny Kavanaugh who was on plainclothes duty says he observed Allen entering the washroom twice. Kavanaugh said he was drying his hands in a stall when Allen peered over the stall door.
The officer's report said that after peering over the stall a second time, Allen pushed open the door and joined Kavanaugh inside. Allen muttered "'hi,'v" and then said, "'this is kind of a public place, isn't it,'" the report said.
Kavanaugh wrote that he asked Allen about going somewhere else and Allen suggested going "across the bridge, it's quieter over there."
"Well look, man, I'm trying to make some money; you think you can hook me up with 20 bucks?" Kavanaugh wrote in the report that he had asked Allen.
The Republican lawmaker, the report said, replied, "Sure, I can do that, but this place is too public."
According to Kavanaugh's statement, the officer said, "do you want just (oral sex)?" and Allen replied, "I was thinking you would want one."
It was at that point Allen was arrested.
Towleroad.com reports:
The Florida Times Union reports: "In his seven years in the Legislature Rep. Bob Allen of Merritt Island has built up a 92 percent approval rating with the Christian Coalition of Florida on issues like abortion, marriage and pornography." LinkWhen Allen was loaded into the patrol car, the statement said, he asked if "it would help" that he was a state legislator.
"No," the officer said.
Soon after taking office in 2001, Allen was one of 21 Florida legislators to sign Gov. Jeb Bush's friend-of-the-court brief supporting the state's ban on gays adopting children.
In March, he co-sponsored an unsuccessful bill that would have enhanced penalties for "offenses involving unnatural and lascivious acts" such as indecent exposure.
