Circuit bending is pretty neat from electronics designer perspective: given the current electronics design state-of-the-art (MCU all the things), how do you design the circuit which responses to the random poking in a most interesting way, without being damaged? It really forces one to bring back that obscure subset of analog-era skills... "This oscillator is almost never used because of bad Vcc-related frequency drift and distorts output in presence of even slight parasitics? Great, let's put it into the design!" (Note that making entire circuit out of DFN parts with 3 mil traces, and then leaving large prominent test points is considered cheating :) )
