Even if you have no musical abilities, your iPhone gives you the tools to create lush, multi-layered tracks in an instant, thanks to the proliferation of simple, speedy interfaces that require neither practice nor patience. Crossfader might be the best representation of this fact to date. With a brilliant concept that uses the iPhone's accelerometer to mix and mash popular tunes, the app won't teach you how to be a world-class DJ, but it will get your next party started quickly.
Building upon the slick, familiar interface it's tweaked to perfection with Djay, Algoriddim has expanded the definition of the multitouch DJ by bringing video mash-up creation to the masses. While certain to increase the ranks of unwatchable videos on YouTube, Vjay adds to a growing list of apps that take us down avenues of creativity we might not have otherwise turned onto.
