I've made a couple of puzzle sites to help cure boredom:
http://www.StickScene.com is a website full of people’s drawings of scenes/posters from movies and TV where you have to guess the name. There are over 400 on there, so that should keep you busy for a while!
http://Puns.StickScene.com is a similar thing, except with puns, phrases, song titles, lyrics, and anything else that can be shown in a non-literal visual form. Currently there are 30 on there, but more are being added every day.
If you're feeling creative then you can make an account and add new puzzles to the sites too. Any standard of artistry is fine, it could be in black and white with stickmen if you want as long as it's guessable!
'Hope you enjoy them! I'm trying to get word around about these sites, so if you know people who would like them then please pass on the links. Thanks!
