Now Daryl, by applying a few simple estimates, you can quickly
calculate that for yourself:
  * the laptop screen or the keyboard in the room corner can server as
gauges for distance
  * the angle between the edges of the room can server to estimate the
focal length
  * the relation of the size in the picture between the (known) size
of the laptop screen and the (known) size of the keyboard can give an
estimate for the distance between them,
  * thus allowing you to estimate the width of one floor panel,
  * thus allowing you to estimate Rick's height

It's as simple as that :-P
