You can download negima desktop mascots at Melfra. You can open one or several at a time and set them to sit on your taskbar or your current window. Click on them and they speak japanese plus you can change their outfits.
Try digital scrapbooking at CropMom. They provide the elements and you just drag and drop them to create your own layout design. It's fun and easy but you need to register to use their site. I like using this to personalize my desktop and you can add photos too.
