Tune's Home Page
Welcome to the humble home of Marcel Tünnissen or Teun as some Dutch
friends call me sometimes.
Originally I come from Holland, but since September 4th 2000 I have
been living in Sweden.
My nickname in Holland used to be Teun, but for a non-native Swedish speaker
that sounds a bit as the Swedish word "tönt", meaning retard, though native
speaker would think the nickname incomprehensible.
Anyway you understand that
I haven't been using my nickname so much anymore
since I moved to Sweden... ;)
Here are some things that I like to do:
-
My biggest hobby, or better my passion is finding and building
polyhedron models. "What's that?!" People
usually ask me. Well, the best way to explain is to show, so have a look.
-
I like to spend my holidays hiking around in
the countryside. Though I must admit that I haven't found much time to do
this lately.
-
A collection of pictures can be found at
flickr
And yes that is all. It is not much, but I am happy with this little
home.
Reactions, remarks, feed back, all are welcome. Just send me an email. My
username is "marcel", which should be added in front of "@tunnissen.eu".
