I guess the gist of the message is to be different when it comes to resumes and cover letters. Here's a few I tried, and so far always worked at getting the interview.

1. Scent the letter (got it of Legally Blonde). Use fruity smells (not durian!) perfume, not heavy musk type. Guarantee u will be interviewed and be asked about it (if the interviewer likes the smell esp)

2. Use different colored papers but make sure its light color so as not to make the fonts unreadable. Light yellow, beige, light blue are good colors and easy on the eye.

The idea here is to show that you're willing to put effort in getting noticed. I once attached a CD filled with my achievements in soft copy and the cover stated 'Various achievements - Will be happy to elaborate further when called'. I sent this to a big company where I know the hirers would have easy access to laptops & computers.

But make sure that the information you put in are not standard MS Office rip-offs like what the rest of the experts in this forum is talking about. Otherwise all you have is just a boring book with a nice cover.
