Trying to let my 3yo try as many different technology interfaces as possible. Mouse: not too bad, especially after reducing sensitivity. Keyboard: WASD is easy to lose track of in a sea of buttons. Controller: requires both hands together, which is tricky. Arguably the left hand is more important too, hard for a right hander.

I haven't found a nice way of reporting "N/N tasks done" in progress interfaces. Users don't like seeing "Baking cakes 10/10 (100%)", especially if the last cake is slow. It's weird to them to see 100% when you haven't finished, but mathematically it's logical.

I'm not sure about teaching OO in terms of shape hierarchies or animal species hierarchies. It might help intuition, but doesn't reflect typical usage IME. If you did model animals in an OO style, you'd be more likely to have base classes or interfaces like IFarmable, IHuntable.
