'Spacetype' is a responsive WordPress Theme suited for creative designers but can act as a great looking landing page too. The theme is actually a multiple page WordPress theme but provides a very respectable one page layout option. I only recently just caught this theme and see it's 60% off on MightyDeals for a limited time only, so act fast. The one page demo is found here.
