Don't mean to be overly critical / nitpicky.... but every time I see this graphic..
my not-horribly-or-excessively OCD, yet atmittedly design-concious brain has to stop, look, and do a double-take at this rendering. Its missing the gap between the "cards", or something.. It would look "more real", maybe, like this quick pixel-hack..
Again, not the end of the world.. Just a suggestion.
