What video games do you play?
You could turn that into a more "active" hobby using an Xbox Kinect or a Nintendo Wii...
But if you want some stuff that don't involve looking at a screen at all, then here are a few suggestions:
1. Learn to make sushi
It's actually pretty easy once you get the hang of rolling the sushi neatly.
Here's a good example:
The cool thing is you can switch the filler with pretty much anything, and get really creative. I like going for some crispy chicken, bbq sauce and rocket. Yum!
2. Make some viral Vines.
Ok, this does involve looking at a screen, but at least you're being creative!
If you keep creating interesting Vines every few days, you're bound to hit the big time eventually with a clip that goes viral.
You don't even need loads of props or help. One of my favorite Viners is a guy called Rudy Mancuso, and most of his clips are of him and his mom in their house:
3. Make a board game?
Yeah, it might sound a bit geeky, but it's actually a lot of fun. Especially if you create a game with lots of jokes that you and your friends will get and enjoy.
