there's a strange tension in that 2 and 3 are the only primes differing by 1, and the proximity of e and π, and the way e and π are everywhere: you almost want to see how things change when e and π are replaced by 2 and 3.
try this: you have four strings, one 2 units long, one 3 units long, one pi units long, one e units long, and you strum them, and then when you use them to build other things, the produced sound transports the strumming elsewhere...
