The Pony Express Mail
During my flight back from New York I experimented with the Mochila desktop client (which is in live code by now). And drew inspiration from Slate (Eduardo Santos), Facebook mail, Mailbox App, Gmail and Sparrow.
This is the end result. I’ve worked with a responsive grid which will let it scale down to 1000px web view before losing readability and turning into tablet mode. I’m actively looking for a developer for this side project.
