Explanation on the logo

This is a very unique logo
which we have brought from Japan
(my wife is Japanese)

There are two figures in the logo
it's just a question about how you focus your eyes::

1. light background and three "anvils"
2. dark background, with a fine geometric figure

This is an inherit from my Japanese Father in law
with 10 fantastic Japanese family-marks

There stands:

maru ni mitsutomoe

maru = round
mitsu = three
tomoe = mark

The world famous Drum-group Ondekoza
are also using this mark

You can see more about this group  here
cllick at "japan" and then "music"

Note:
The Ondekoza-Logo  is not the same
