How to get rid of blank walls

OK, you are no longer living in a dorm. You do not lead a completely joyless life. Nor do you live most fully when playing World of Warcraft. Failing to put anything on bare, white walls, like in the picture above, sends a signal to potential sex partners that you may be at least one of the above. So what to do with bare white walls to make a good impression?
PAINT:
Obviously, painting is a good option if you’re allowed; a hardware-store gallon of paint is only about $20, painting most rooms only takes a few hours and not having your wall be dorm-room white does wonders for your quality of life. But use really bright colors sparingly; they look pretty on the paint chip but are way darker than you’d expect when covering an entire room.
ART:
Hanging art is another option. However, keep in mind that if you’ve seen a piece of art in the apartments of more than a couple people, you should maybe keep looking for something more interesting. For example:

None of the above posters should be found in an adult home. The message you want to send is “I am interesting and have my post-collegiate shit together, potential sex partner” not, “Dude, I just discovered this SWEET underground artist called Dali, oh no WAY you’ve heard of him too? BTW, don’t you totally love beer/college/some movie/faux-arty lesbians? Because I totally love beer/college/some movie/faux-arty lesbians.”
