Barcodes can be quite resilient to redaction. Not only is the pattern a strong visual signal, but also the encoded string that often has a rigidly defined structure. Here I present a method for recovering the data from a blurred, pixelated, or even partiall...

Neat! And actually a lot less kitchy than a lot of LED decorated clothing i've seen.

It has been so warm and wet in Indy that this hasn't happened here. (Yet.) Usually get a deep freeze in January, though.
