Thanks Ryan, the sprite trick is very handy.
@Ryan: yet again you've done a great tutorial job. Thanks for covering this episode with Spree. In version 0.80, we plan to have the namespace for the sake integration with other such as RefineryCMS. I hope you will create another tutorial on Spree integration.
