Visual Turing (freeware) http://lib.giveawayoftheday.com/Visual_Turing_200693/ Visual Turing Machine, is a tool for visually designing Turing machines. This means no coding in abstract scripting languages, but simple point&click design. It uses the a..z symbol set, plus the "empty" # symbol, and also simulates an infinite tape.
