Word cloud as image (no tags)

Hi,

I want to have on my landing page several word clouds. I want to have them instead of some pics, e.g. if I have the sample page and then I would like to have in the lower section instead of the small pics of people a Word cloud out of the content which is behind. So, the cloud is generated out of the content dynamically. Best would be if I could specify if a pic or a word cloud is displayed.

Is this possible? Does a plugin like this already exist? If not, some recommendations for a starting point? Ideas what might be possible and what not are welcome.

thx maria
