Early U.S. Presidents in Today’s Suits

Digital artist Magdalene Visaggio uses her iPhone to transplant the portraits of U.S. Presidents into photo software and gives them modern clothes and haircuts as if they were U.S. politicians today. See her Twitter feed and meet George Washington (above) and others. Scot mountain biker Danny MacAskill is arguably the best bicyclist of any type in the world. Here are two video clips [each six minutes long] of proof. In the clip above, MacAskill treats mountains the opposite way rock climbers do: finding new and challenging routes to descend the peaks. And in the clip below, a tour de force, he cycles down the rooftops to the sea in my wife’s hometown of Las Palmas de Gran Canaria.

‘IsoTruss’ Bikes Beyond Carbon Fiber

vcrosbie

I’ve been amazed by the past 20 years of progress in racing bicycle technology due to advance materials.  The first reasonably affordable titanium-frame racing bicycles starting appearing in 1990 and shortly after 2000 the first reasonably affordable carbon-fiber-framed appeared. We now have the first new advancement: carbon fiber bicycle frames that aren’t entirely solid. Above is a photo of the $10,000 (US) Delta 7 road bike. The junctions in its frame are made of regular carbon fiber but the main tubes of the frame consist of an open latticework of carbon fiber/Kevlar strings woven into a network of isosceles triangles. That latticework is up to 12 times stronger than steel but weighs ten times less.
