Microsoft PopFly

Popfly is the fun, easy way for anyone to build and share mashups, gadgets, Web pages, and applications. Popfly consists of two parts:
1. Popfly Creator is a set of online visual tools for building Web pages and mashups.
2. Popfly Space is an online community of creators where you can host, share, rate, comment and even remix creations from other Popfly users.
