I recently purchased an all-in-one scanner/printer/copier, and although the product is a bit of a pain in the neck in getting hooked up on a GNU/Linux system, I'm very pleased with the results. I spent my entire Saturday sitting in front of my computer scanning and touching up old artwork of mine that was unfortunate enough to land on a non-digital medium.
What really thrilled me though was a newfound abillity to restore damaged work. Many years ago, a hobby of mine was drawing mazes. I had made quite a few, but sadly lost several to water damage. I couldn't throw them out though; some of them were my better doodles and I just didn't have the heart to drop them.
So I was as giddy as a schoolgirl when I realized that I could now scan them into my computer and remove the atrocities that nature had bestowed upon them. The images on the right are a "before and after" of the work done on them. I'm so pleased with the outcome that I've added a new category to the artwork section of this site, with an assortment of mazes available for viewing (and solving!).
On a side note, I'll mention here that the signature shown on the image is not actually my real signature. Call me paranoid, but I'm sure enough of my personal information is already floating around online that putting my real signature out there would be somewhat foolhardy. With that in mind, I took it upon myself to replace my signature on the images with a signing of my name that doesn't match at all (yes, even in that "original").
