 The Train by Vivian Ha*/

/*interactions: 
 move mouse right to open the train doors, 
 and move left to close them.
 click mouse to flicker the lights 
 and invite a visitor
 (he's easy to miss, so if you can't
 see him, click a bunch of times 
 until you can make him out*/

 purpose of "bg patch-up" is to colour in necessary
