+   I love e-ink displays!
+   The mathematical philosophy here is using deterministic logic (Bayer matrices, arithmetic hashing) 
+   to simulate physical chaos (paper grain, ink bleed). I picked up these concepts in a course 
+   and this is easily the best real-world application of them I've found. 
+   It works brilliantly-looks like real paper, killed my eye strain, and even reduced the insane 
+   reflections from my glossy surface display.
