You can now make your own personalized Kleenex Oval boxes. Compose your box on the My Kleenex website. You get a ton of flexibility including many different back grounds, access to clip art, frames, the ability go upload photos (or any jpg or png), and add text (choosing from the many fonts and colors available). Your finished box is shown to you in rotating 3D. This site recently won and Adobe Site of the Day award.
I haven't come up with a good reason why I would want a photo on a Kleenex box but it's a fun idea. From the US it only cost $4.99/box plus shipping, which isn't that much of an increase over a regular box of tissue. I've always liked the personalized photo stamps but they are so much more expensive than regular stamps that I can't justify it.
