The first two ideas are entirely visual and responds to the hand swiping motion.
For this one, I think there are lots of opportunities for details to animate the tilt of boat, ripples in the water, rising sun, etc.
I wanted to have random nasty things thrown on the car window, and users can activate the car wiper by hand swiping motion.
This concept incorporates presence, swipe, and time. Users start with an egg that will eventually hatch with ones presence, which will also impact the background color to become warmer (the eggs need to be kept warm for them to hatch). Once the egg hatches, the user can interact with little ducklings with hand swiping gestures to play. The duckling needs a certain amount of love and care to mature. Lastly, when the duck grows up, it will lay eggs and users can choose to restart the game by clicking on an egg. Or, users can remain in this stage and interact with grown duck.
