The author of
Valgetal and Matego
My name is Rinze. I've studied applied physics
and I've been working as a teacher for a while.
At that time I ''fell in love'' with educational
programs. I think it's quite refreshing to play
sometimes with a nice program. My ideal software
is of course instructive, with a clear interface,
but it must also be a challenge. That's the
reason I always try to make them like a game with
a possibility to get a high score.
