A very cool video promo for Ruby on Rails and Mac OS X, or should I say: 37 Signals & Apple :-) Either way, very cool!

Consistent Functionality
to RoR developers across Virtuoso, Oracle, SQL Server, Sybase, DB2, Ingres, Informix, and others without compromising performance or cross platform portability.
