The difficulty with kubb is that a game does not have a set duration, therefore it is hard to keep track of which teams are 'available' to play a 'next round'.
The software enabled the organisation to enter scores remotely from the playing-fields, the system then calculated which games should be played next. Giving insights in, which games are taking to long (and are a bottle-neck for the rest of the tournament) which games have been or should be announced by the speaker, etcetera.

Inspired by the increasing negativity towards train-conductors (because of late/broken trains), I made a little thank-you card for them stating that it's not fair that they receive al the complaints for things they are not responsible for. I made thousands of them and distributed them on trains and stations.
The reactions of train-conductors (via e-mail) were great and showed that they really appreciated the action.
