GREAT CAESAR'S GHOST!  That is INSANE!  WOOOOOOOOOOOOO!!!!!!!  Somebody call Tom
Brokaw, this is the news of the CENTURY!  Dave is the coolest, Dave is the
coolest, Dave is the (well you get the idea)!

Seriously, is this a publish-worthy result, or have I just not seen the right
papers?

Details, schmetails!  <1fps ==> 50fps!  Bother me tomorrow, today I'll buy no
