Well, I hadn't meant to go on a time-traveling jag, but I just find this stuff amusing. You know how seeing patterns of significance (faces, religious iconography, etc.) in ordinary patternless objects can be summed up in the single word pareidolia? Well, apparently there's a term for the current trend of anachronistic pareidolia from films and such, and near as I can tell it's coined by Joshua Glenn: the Pluperfect PDA. (Via io9 again.) It's pretty amusing since PDAs have been around such a short time and, considering the rate of technological evolution in my lifetime alone, will probably be replaced by something else ere long. But hey, people didn't see Jesus' face in toast before Jesus was born, or before toasters were invented. Seriously, guys, next you'll be talking about how Captain Kirk signed off on proto-iPads from the Enterprise bridge.
