Recently on Offworld: an ode to the jetpack, rusted steampunk adventures, Tetris bejeweled

Recently on Offworld, our Ragdoll Metaphysics columnist Jim Rossignol takes us through an illustrated history of one of videogames' best mechanical conceits: the jetpack. From The Stamper Brothers' original JetPac, to Exile, to Tribes, Jetpack Brontosaurus (above) and beyond, he looks at how the 'pack has let us "explore strange new worlds where the sky is not the limit, and where the vertical axis is as just as essential as the horizons that lay all around us."

Elsewhere we marveled at the intricate rusted ironworks designs in the latest video of Amanita's upcoming adventure game Machinarium, saw Minotaur China Shop (and Jetpack Brontosaurus, coincidentally) creators Flashbang poke gentle fun at Braid creator Jon Blow, and found a wonderful series of T-shirts based on the glitched-out boot-up sequences of arcade games.

And for our 'one shot's of the day, two more fantastic pieces from artists appearing in the upcoming Autumn Society games/art gallery show: Zelda's Link aims for the eye, and the Swarovski crystal-studded queen Tetrisina.
