Now that we have multi-layer floors, we can more easily make variations on a theme.

E.g. the current four carpet tiles I made can be done using three layers:

a) base color (currently red or blue)

b) outer pattern (fleur-de-lis or nothing)

c) inner logo or pattern (MS logo, or center fleur-de-lis)

Moving to doing it this way means that the total number of possible floor
combinations is a*b*c for a+b+c images. This also should be done for many of the
other tile combinations.

It would then be easy to increase the number of options. Adding another base
color (say green) means the options increase by b*c .
