Google Roll it

This would be a delightfully devious opportunity to increase Android marketshare.

Do-be-evil mode pseudo code:

  if $user_agent =~ /iPhone/
    $ball_velocity = $swing_force - $number_of_swings
  end

Gradually increase the force required to attain equal velocity until iPhone reaches any given value of wall.

Played for about 1 minute, then my MacBook's fan started spinning like it was trying to take off.

After rolling, it got stuck at "Please Wait". Fail.
