Klint Finley:

It took him six years, but Siegel, an engineering student at MIT, now has a solution. It’s called Carduino, and it’s the first product from Siegel’s new company CarKnow.
 This tiny device plugs into an automobile diagnostics port, letting you equip your car with all sorts of tools you otherwise couldn’t. You can set your windows to automatically roll up when the weather changes, tie your doors to a smartphone app that lets you lock your car from across the internet, or, well, dream up something no one else has ever thought of. The idea is that anyone can use the Carduino to build any app they like.
