# City block

> Hamlet pack scene: a city block on its own island. A glass tower with a blinking antenna, a brick walk-up with a fire escape and a water tower, a three-setback art-deco tower and a corner shop under a striped awning, ringed by a road where cars drive round past street lamps and trees. At night offices light up at random. Tap and the tower's windows spell a heart. Raymarched in WebGL.
