We here at Drunk Bear Fans are always on the lookout for innovation in tailgating. I saw this Daquiri/Margarita machine running at the tailgate next to us. Note the cord hanging off the back - they brought a portable generator to run the industrial sized monster. Also of note are the svelte shape of the woman running it and the desperate patron chugging his cornwater so he can get a foofy cocktail.
Also, in the innovation category, my wife got this for me at a county fair or something, my very own beer holder that clips to your belt. It is made out of leather and was a big hit.
