Twitter has been throwing caution to the wind lately, what with the addition of random tweets to users' timelines, "Buy Now" buttons, and a font tweak that set the typographical world ablaze. Now we're seeing an interesting new use of Twitter cards in advertising: Acura has built a rudimentary configurator for its new TLX model right into a tweet, which lets you choose an engine, a drivetrain, and a color before offering the option of sending an image of the kitted-out vehicle to your followers.

Ironically, Acura isn't really known for innovating on design — but it can apparently innovate on social media. The configurator even works on Twitter's mobile apps (though not in embeds, it seems).
