Looking for Ruby on Rails applications for a demo

Hi all,

I am looking for most popular ruby on rails applications that are
currently implemented, and also who is using RoR to build new
applications

Thanks

Look around is the best advice.

Check out http://github.com and see what you can find there ... many
repos to look at and learn from. Hop on to the IRC channel and ask
what people are working on.

Spree is an interesting ecommerce application. It runs
out of the box and has a growing community.
