What is the MySQL app used in the 15 minute weblog video?

On the "Create a Weblog in 15 Minutes" screencast on the Ruby On Rails
site

http://media.rubyonrails.org/video/rails_take2_with_sound.mov

There is a really nice looking MySQL gui interface app. Can anybody
tell me what the app is? I'm actually looking for a Linux version.

That is CocoaMySQL, available from http://
cocoamysql.sourceforge.net/. Since it's written in Cocoa, there isn't
a Linux version.
