Trajektoria - a minimalistic zero violence PC-game.
A particle moves in a field. Test your ability to estimate it's future position.
You may wish to play competitive, finishing as quick as possible. The game can be made harder if you activate the annoyers or made easier if you turn on the tracking option.
A more contemplative approach might be to just enjoy watching the harmony of the field and the particle.
