PixyMe (US $1.99) brings a static version of this technology to your iPhone or iPod touch. This beautifully designed and rendered app lets you incorporate any name or short phrase seamlessly into an eCard or postcard, appearing as though it were part of the photograph. The resulting personalized photo can be either emailed, sent to Facebook, saved in your photo album, or sent as a high-quality physical postcard to any address in the world. It works remarkably well, as you can see from the picture on the right and the gallery below.
It's unfortunate that this app has the all too common problem of dropping you into the fray with scant instructions. That would be okay for a simple one-trick-pony, but this app is fairly complex and has functions that need explanation. There is an info screen at the end of all the options, but all it gives you are the raw basics and a link to get to the PixyMe site. What you probably don't know is that on the site is a great introduction and all the information you need to get started quickly in a video tour. You can view it at the end of this post. I feel that this video should be incorporated into the app or directly linked to rather than dropping you at the site. That's my only complaint. The rest of the app is a delight.
