A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the base pitch of the tone moving upward or downward, it is referred to as the Shepard scale. This creates the auditory illusion of a tone that continually ascends or descends in pitch, yet which ultimately seems to get no higher or lower.
It has been described as a "sonic barber's pole". The acoustical illusion can be constructed by creating a series of overlapping ascending or descending scales.
Boolean logic, originally developed by George Boole in the mid 1800s, allows quite a few unexpected things to be mapped into bits and bytes.
The great thing about Boolean logic is that, Boolean logic is very simple.
Logic Gates: NOT, AND, OR. And combinations with these three to create: XOR, NAND, NOR and XNOR.
With these simple gates you can build combinations that will implement any digital component you can imagine.
I combined these two in an interactive and informative article to show you a bit more logic fun:
