[Moose-dev] Tag cloud around an avatar

Hi, I would like to create a tag cloud around an avatar taken from the public profile of a social network (twitter). For that I would like to know if is possible to make 3 things in Roassal: 1. Put a tag cloud with some layout/form (for example around an object). 2. Put a raster image (the avatar) in the center of that tag cloud. 3. Exclude some words from the tag cloud. I will be making my explorations tonight and tomorrow morning, but any pointer in the right direction will be greatly appreciated. Cheers, Offray
