We give a new proof of the following interesting fact recently proved
by Bower and Michael: if a $d$-dimensional rectangular box can be
tiled using translates of two types of rectangular bricks, then it can
also be tiled in the following way. We can cut the box across one of
its sides into two boxes, one of which can be tiled with the first
brick only and the other one with the second brick. Our proof relies
on the Fourier Transform. We also show that no such result is true
for translates of more than two types of bricks.
