New technology really can help you eat healthier. I was on the road for some time and finally found a fast food restaurant. I walked in and they had replaced the traditional printed menu sign over the counter with big digital displays. Unfortunately the displays were polarized vertically. I was wearing sunglasses that were polarized horizontally. The result was a pitch black display. If I took off my glasses, everything was blurry. If I tilted my head, I could kind of see the menu. I took this sign as a sign that I should not be eating at fast food restaurants and kept driving.
