Cool Thing: Bingo Card Generator

Found this while looking for writing prompt bingo card communities. It's a bingo card generator that you can either use to create your own bingo card (i.e. give it a list of prompts of your own choosing) or use one of a variety of pre-generated lists. It allows you to create cards as small as 1x1 and as large as 7x7.

It's located here: http://an.owomoyela.net/fun/bingo_generator#generated_card

I found it thanks to http://allbingo.dreamwidth.org/
