Maybe this should go to my photo blog, but since it has an interesting software development aspect, let's post it here:
SEAMonster is a .NET based implementation of a fairly recent idea presented in SIGGRAPH 2007 called seam carving. To put it short, it means resizing images in a way that preseves meaningful areas of the image while compressing/deleting the other parts as needed.
Have to download the code and play with it with my own images, putting it in codeplex is also a great idea :)
