You know QR codes? Those square barcodes used in advertisements that one can scan with a cell phone to learn more about a company or get a discount? Well the folks of NYC resistor, a hacker collective with a shared space located in downtown Brooklyn, challenged themselves to make their own QR code out of food! On their blog they explain:

The team that makes the most righteous, edible QR code that actually recognizes using google googles wins the prize.
Naturally, the prize started with “W” and ended with “affles”

From a customized waffle iron to a QR code composed of Jello, you'll be amazed at the techniques employed by the hackers.
