Advertising agency Redpepper wanted to spice up Siri's skill set. Naturally, the tinkerers turned to a monster truck toy and a can of Dale's Pale Ale. Hence, Beeri was born.
Beeri is an RC truck that has been modified to check the Twitter account @beeribot over Wi-Fi for new tweets with the "pour" command.
The makers achieved this by using an onboard open-source Arduino physical computing platform (as did this tweet-printing toilet paper dispenser). Beeri also has an unopened beer can strapped to the front bumper.
Redpepper created the @beeribot account and assigned a contact to it on the iPhone 4S. The soon-to-be-beer-drinker tells Siri to tweet, "Could you pour me a beer?" to @beeribot.
The truck picks up the word, revs itself up, and smashes into a sharp object to pierce the beer can. The frothy beverage flows down through a hole and into a pint glass below.
This is just about the most impractical and convoluted way you could possibly pour a beer. Most of the precious liquid goes up in foam. You have to reload the truck every time. It creates a Gallagher-style mess. It's also awesome and may be the most compelling reason yet to get an iPhone 4S.
