One of my favourite examples of what can be done with RIA’s, Aviary, is now out of private beta.

Their new website is www.aviary.com.

My favourite app is Peacock, a pattern generation tool that makes it really easy to create complex structures based on images, such as this one: http://aviary.com/artists/mpeutz/images/coffee_3 or perhaps all generated, like this: http://aviary.com/creation?fguid=c1bc6fec-5aae-102b-a5ee-0030488e168c

I can also recommend looking at Meowzas work, impressive…
