Unity in 24 hours is pretty cool. If you haven't done game development before this will open up a lot of possibilities for you and it's pretty fun. For example, not only will it show you how to create 2D and 3D games but it's pretty easy to turn a 3D game into a virtual reality game. But especially with virtual reality it doesn't have to be a game. So it's actually super practical in my opinion.
