Computers have allowed companies to streamline the process of offering endless customization options, though ironically if you're reading this on a Dell, you're clearly from a time before these options existed. Stop stealing our future thoughts!! Use your comp to customize the bag you carry it in, at Caseable.
\Letting you create fully customized laptop carriers via a slick design interface boasting enough options to allow for over 20,000 unique looks, Case was just launched by a duo of German designers living in Brooklyn who felt "something missing in the sleeve market", but couldn't figure out how to steal Bill Belichick's game day look. Start by picking your dimensions (sizes avail for 10 distinct PC/Mac notebooks) and whether you want your waterproof neoprene job slim, or slightly bulkier thanks to a faux fur lining; then choose from 45 diff colors for the front & back panels, 13 for the side/zipper, and five for the optional handle, but not your online handle, as Doggystyle69XXX is not a color. Next, upload photos to size and drop anywhere on either panel, and add text in a variety of recognizable fonts, including the one used for TMNT; they've also built a randomizer that'll generate design elements from color schemes to images, as nothing says "you" like stock photography.
If being creative is too tough, there's an entire gallery of premade options, from a Tetris-themed job, to a blood-red number scrawled with "Video Killed the Radio Star", which, if you're reading this from a Dell, probably hasn't even come to pass.
