Unlike many of the doomed projects on Kickstarter, these cards are now a real product that you can buy. And, boy, do you need to buy it.
It's essentially Top Trumps-meets-computer science, and features "30 CPUs from the last 40 years [that] have been picked for their contribution to computer history". A single deck of the cards costs $US12.79, and that is without doubt some of the best money you will ever spend. [CPU Wars via Boing Boing]
