There's more on the website but these are some of my favorites. I added them to my "Fashion Wallpaper" folder at home & work. I have quite a few vector images. In case you don't know about vectors, they are the cleanest form of digital art. You make seamless shapes with lines and then overlap them, adding gradients where needed. I've done a few logos with them and perfection only comes with practice. I'm no where near this good so I totally respect vectors as a form of digital art, especially when they're this cute.
And if you're as "shallow" as I am, then you might need a matching phone wallpaper. They're sized at 240x320 b/c I have an iPhone but your phone can resize them automatically. If you can't upload them directly to your phone, e-mail them to your phone as media messages. The best way to get this e-mail is to send a photo from your phone to your e-mail. Then you can reply with the wallpaper as an attachment.
