Do you knit or cross stitch or any of those other hobbies that keep your hands busy? I would try one of those. Also, jigsaw puzzles or playing cards. Anything that keeps your hands and your mind busy should help pass the time.
Do you have other people in your household? Can any of them play board games with you?
And, definitely keep up the walking. Walk for an hour a day. When you're given the green light to exercise again, you'll be surprised at how fast you get your strength back. I took 6 weeks off last fall and when I got back to it, I was shocked at how little DOMS I had.
Good luck on your recovery!
