There's this excellent website and project being run by Channel 4, the UK broadcaster. Basically they're encouraging people to tell the stories of incoming cultures to the UK by building a series of websites. To this end they're running a series of workshops across the UK. They've already been to Bradford, Bristol and are running some in Wolverhampton at the moment. I wish they'd had something like this when I was a kid.
These are some of the sites they've made that I liked:
Traditional Asian Drag Queens
Pickled Cabbage (Serbians in Bradford)
Turban - Harphuman Singh's story
