For this week's Crave giveaway, we're offering a $250 in chocolate from Chocomize, a site that lets you get creative and design your own chocolate goodness.
We're previewing the future one concept video at a time. We look at Samsung's future in which transparent tablets conjure holographic magic. Toyota's squeaky-clean future makes us feel dirty. And to even things out we revisit 1939's vision of the year 2000.
These are the official rules for CNET's Crave blog giveaway of the week contest.
