Intwined Pattern Studio - Crochet chart creator. This thing is sweet with a price of $28.60 from Knitpicks.com (http://www.knitpicks.com/tools/intwined-pattern-studio-software.html). I've linked to the page with a video demo. It not only creates a chart, but will output the pattern for those who can't read charts Or for those who wish to sell their patterns. Knitting and crochet are included.
