From the Rays of Light blog:
Last year long about November, Microsoft purchased a small Hong Kong-based software firm named Creature House. One of their principal products was a vector graphics editing program called Expressions 3. Primarily a Mac product, they also had a Windows version; both versions received very positive reviews. Microsoft’s disposition of the developmental version of Expressions 3.3 is totally unexpected. They are currently giving away both the Mac and the Windows versions for free!
