It's bring-out-your-inner-artist day at iPhoneGuide today. Like Picture Sketch Pro, My DNA allows users to create something unique from preexisting data. In the case of the former, the data comes in the form of photo. For the latter, it uses your personal information (i.e. name, birthday & height) that does the trick. What My DNA ($1.99, available here) does is use your info to create colorful pseudo-genetic barcodes that you can customize. You can use your 'DNA profile' as a profile picture (for twitter or Facebook, for instance), eSignature, icon, art display, or wallpaper. No one else will have the same picture, according to the developer.
