Design looks great, though I've encountered a bug. When I click "Get Started" the signup modal displays. Clicking the browser's back button after this removes the signup form, but leaves the modal in place. Continuing to hit the back button appears to toggle display of the signup form. Hitting the 'x' in the top right corner will dismiss the modal.
