For the first assignment, I made an interactive web app that allows people to shake their phones and decide what to eat today.
You can open this page on your phone: http://yining1023.github.io/whatToEat/
My code is here: https://github.com/yining1023/whatToEat
I used device orientation/motion API, shake.js, and emoji CSS.
You can see the video I posted on Instagram.
Here's some screenshots of my phone.
