Visuwords is a free version of a service similar to what Visual Thesaurus does.
If a regular thesaurus just isn't doing it for you today, or if you're more of a
visual thinker (utilizing pencils and notebooks, etc), then check out Visuwords.
It organizes the connected words as a train of thought. Throw as in confuse or
throw as in toss - it puts those word sets into two different bubbles.
It's a nice change and new context if you're really stumped in describing the
current literary action.
