That's why BoxWave is calling them Matrix Crystal Slip cases. I also assume someone over there downed the red and blue pills (or crushed, liquefied, and smoked them) when Morpheus wasn't looking because the "regular price" of each case is listed at an outrageous $32.95. An ongoing "web special" reduces them to $19.95 each, which the Oracle reminds me is still more expensive than other TPU cases with patterned backs.
The green case is the most Matrix-y out of all of them due to the color, but you've got to be squinting and waving the case really fast in front of you to start believing that there is no spoon.
Each case is made of "anti-slip and cushioned material" that I assume is TPU and features a "cut-out design for the touchscreen" so you don't have to use your mind to control the phone.[BoxWave] Thanks, Dave!
