In Holland we have (or at least had) monthly editions in which I have
seen such puzzles. A personal webpage in Dutch containing a similar
puzzle is
http://members.lycos.nl/puzzel/logica.html#Puzzel3
I suggest you mail the author of this page for more information on this
type of puzzle.

All the way at the bottom of the aforementioned page you'll find a
diagram, with the following text (translated):

House-Tree-Animal
In the diagram, 16 connected triplets have to be drawn. A triplet
consists of a house, a tree and an animal, in which the tree always is
at the centre. Similar symbols can never be found in adjacent squares,
not even diagonally. The three symbols can be placed horizontally,
vertically, or 'cornerwise', but not diagonally. The digits on the right
and bottom indicate the number of symbols in the respective row or column.

If you think you have solved a puzzle, mail it to me:
karengerr...@dolfijn.nl. Make a picture of your solution (e.g. jpg) to
send it in few bytes and with a good result.
