Read! All those books you own but have never read, pick them up and enjoy them without feeling guilty. If you do not own any books then sign up for a free e-Book library and start with all the books you should have read but never did. I would give my eye-teeth for a few days of guilt-free reading 
PS: while reading, you will inevitably think of a photographic project to do when you can get out again, too.
PPS: if I was trapped inside I would try and find time to learn how to take apart, repair and re-assemble vintage lenses. I've always wanted to do that..... lots here in France at jumble sales, too.
