This video shows Oli Lemieux practicing on the trampoline wall of Cirque du Soleil and I've watched it twice already. I keep searching for clues that it's just a cleverly edited video, that someone couldn't possibly really do these stunts.

Despite all the discussion of what the human body can be pushed to do, I feel feel a sense of disbelief watching Oli jumping around. I know that he's a talented man and that this clip is almost certainly not edited in ways that enhance the stunts. But a part of me desperately wants the video to be fake, because, despite the many years of practice it must've taken him to make everything look easy, Oli has forced me to realize my own personal limitations.

It's impossible not to love the concept of doubleTwist, the all-devices-welcome quasi-iTunes music manager, but up to this point the software has been pretty barebones. Now, things are gettin' ser-i-ous: doubleTwist has a built-in music store, courtesy of Amazon.

To put this into context, doubleTwist debuted not just as an alternative music manager for people with or without Apple players, but as a giant, coded jab at iTunes, Apple, and the way they do business. After launch, DVD Jon, who created doubleTwist, spent a few months waging a small-scale PR war, hanging Apple-baiting banners in San Francisco and parodying their famous "1984" ad. With Amazon MP3 store integration, that ad's promise—to "bring you choice"—has come true, and it's worth a thousand PR stunts

As has been the case with every other aspect of doubleTwist, the music storefront looks like a simpler version of the one in iTunes. Navigation and searching are about as simple as they could be, as are downloads, which only take a few clicks. The whole experience will be familiar to anyone weened on Apple's bloated beast, apart from a few things: Amazon's album prices are often lower than iTunes', and of course, you can immediately sync any music you download—there's only music, by the way—to practically any device you own, be it a Pre, a BlackBerry, a Sandisk, an iPod, or whatever.

The first version is Mac-only and tied to Amazon's US store, but Windows (and international) versions are on their way. [doubleTwist via Techcrunch]
