Here are some half and quarter tiles that I’ve made for the WP7 home screen. Simply go to the link below on your WP7 device, tap on an image you want and pin the site to your start screen. This was inspired by the custom organisation tiles at http://blog.iqagency.com/?p=3751. At the moment they are only blue on black, but you can get the PSD below to make your own.
