What's that word?

I've been playing with a couple of visual thesaurases – or is it thesauri? – online. They're excellent for feeling your way towards the word you're looking for in an intuitive way. The first one is the Thinkmap Visual Thesaurus.

You can try it online and either subscribe to it or download it. It's extremely comprehensive and allows you to chase a word depending on nuance – if you click on one of the little circles it opens up another cluster of meanings.

The second one is the Visuwords online dictionary. It's free and, while it's not as sophisticated as the other one, it works along the same lines.
