Very nice! I'd recommend that the landing page either shows an example right away (the Carl Sagan one is great) or make it more obvious to take a look at one first - took me a minute to figure out what this was for, but the example made it click immediately.
Thanks for the feedback! Didn't you get a highlight and text banner telling you to either enter a date or select an example? Or do you mean even then it should be more obvious?
Was it that the splash screen quote took too long too?
