Cool Project Ideas

I have completed the first curriculum (Responsive Web Design) and think coding is really cool so far. But I don’t want my learning to be strictly transactional and boring. So in order to keep it interesting and mostly for fun i am looking for cool ideas to implement with my HTML, CC, and JavaScript skills.

So some questions for y’all (whoever wants to respond):

  1. What’s the coolest thing you have built in JavaScript?
  2. What’s a fun idea I could build using JavaScript?

Thanks in advance for your time!
