Rendering tweets with Play2.1

Tweet Controller

package controllers

import play.api.mvc.{Action, Controller}
import play.api.libs.functional.syntax._

import play.api.libs.json._
import play.api.libs.concurrent.Execution.Implicits.defaultContext
import play.api.libs.ws.WS

case class Tweet(from: String, text: String)

object Tweets extends Controller {

  implicit val tweetReads = (
    (__ \ "from_user_name").read[String] and
    (__ \ "text").read[String]
    )(Tweet)


  def tweetList(query: String) = Action {
    Async {
      val results = 10
      val responsePromise =
        WS.url("http://search.twitter.com/search.json")
          .withQueryString("q" -> query, "rpp" -> results.toString).get
      responsePromise.map {
        response =>
          val tweets = Json.parse(response.body).\("results").as[Seq[Tweet]]
          Ok(views.html.tweetlist(tweets))
      }
    }
  }
}

routes

GET     /tweets/:query              controllers.Tweets.tweetList(query: String)

scala template:

@(tweets: Seq[Tweet])
@main("Tweets!") {
    
Tweets:
    @tweets.map { tweet =>
      

        
@tweet.from: @tweet.text
      
    }
}

So invoking following URL http://localhost:9000/tweets/playframework now gives me the last 10 tweets containing playframework (case insensitive). I think it's pretty slick how little code is needed.
