Cool websites that school and work won't block?

My school has a pretty simple internet blocker. Most obvious game sites like pop cap games are blocked. Does anyone know some cool sites that won't be blocked? Cool websites that school and work won't block?

Depends on the blocker that your school uses, my school for example won't let almost any website through with out a working proxy which is rare, hell the schools home page has even been blocked for "Adult and Pornography" lol.
