Hi! I'm a long time user and fan of Gnome (since the 0.13 release) and a new fan of Ruby. So far I've only provided a few small patches, and contributed some documentation. My current project is adapting the GTK+ 2.0 TreeView Tutorial to Ruby. When I complete that I hope to help implenet new widgets in Ruby/GTK.
I have also been developing an audio player utilizing Ruby/GTK, Ruby/GStreamer, Ruby/Libglade, and Ruby/Libgda. In the near future I plan on utilizing Ruby/GConf for preferences, and eventually Ruby/PanelApplet when it becomes part of the main distribution.
