If you have an iPhone or an iPod touch – visit this site -> Poolga Hundreds of funny / cute / pretty / subversive / understated / interesting wallpapers to chose from. There’s something for everyone.
You can also visit the site from your phone, for an extra quick dose of designery goodness.
These wallpapers are free for personal use – if you see some that you particularly like, you can click through to the designer’s website, and investigate their work. I find it’s a glorious way to spend half an hour on the sofa when Anthony insists on watching football. Here’s the link again: Poolga – clicky clicky!
