My wife is incredibly good at MineSweeper so I made her a clone for Valentine's a few years ago: http://valenmines.herokuapp.com/

I used the project as an opportunity to learn ReactJS. I thought she would enjoy the twist of the layout being heart shaped instead of rectangular but I think she's a purist ;)

That benchmark run is about a year old. Yew is v0.15 now (v0.7 came out a year ago) and has improved substantially (and has keyed components now).

This looks awesome! Also a good resource for building ember ui components. Great job!
