Reaching Out (Binary Codes)

This may look like a video that teaches about binary numbers, but it also contains steganographic codes (hidden messages). The lyrics explain how the main code works, but there are many hidden messages in the video using various musical and visual encodings. The codes only use binary numbers, and the video is intended as an extended exercise in working in binary. Some simple warm-up songs and more information are provided at csunplugged.org/modem. The main message is coded in the tune of the song using the same idea as a modem a high tone is a one, and a low tone is a zero.

If you decode some of the messages, please don't post them in the comments, so that others can enjoy the challenge too. The hidden messages tell you what to do to get recognition for decoding them.

The title of the song is from the theme of the 2011 SIGCSE conference.
