Online generators have been on the web for donkey's years - often infringing copyright rules but always giving the ordinary online mortal a chance to imagine.

To pretend that their name is up in lights on a movie billboard, that their own band is playing on their iPod or that they can have a snazzy animated logo without a sniff of programming knowledge.

Having explored and used them in the classroom, I can definitely say that generators are an under-used web resource and are great for independent learning.
