If I had known better ....
Day 22 is a clock that tells time with QR codes and also recycles some of the sayings from the fortune clock of day 15. You might be thinking, "wow! a qr code generator!" and rush to the source to read it, but you will be disappointed. Instead there are 8,640 bitmaps stored in the resource file, one for every ten seconds in the day. I started writing a reed-solomon encoder, but decided that given the limited problem domain and the resources.h from yesterday, that it would just be easier to pre-generate all of them.
