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

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.

Looks like cocoamysql ( cocoamysql.sourceforge.net ) to me.

I think its CocoaMySQL, a Mac-only GUI client.
