A new entry to the Mozpad Universe: Open Mashups Studio.

From open-mashups.org :

Open Mashups is a unique solution that empower any creative user to design, run and share its own applications. These applications are built by assembling components.

Take a look at the screencast ! It's awesome (notice the SVG related work) !

Open-Mashups is a Firefox extension based on technologies such as SVG, XBL, XSLT and XPCom. The author of the extension (Fabrice Desré, from Orange Labs - France Telecom) told me a future version of this tool will be based on XulRunner in order to provide a cross platform Desktop widget engine :)

Try it ! (Firefox 3 required)
