There was a paper recently accepted into Physical Review Letters which describes about numerical simulation of merging black holes in binary black hole system and also shows the evolution of black hole spins. The paper itself is only available as an abstract <Flip-flopping black holes> the rest being hidden beyond the paywall but the video of the simulation is pretty cool and the music is awesome too.

It is interesting that the electronic ' flip-flop' was one of the first ' valve' or 'transistor ' circuits , that gave the big kick into computers .

 

Being a binary system , whereby positive feedback was used to push the opposing stage ( transistor ) into an alternate state . Namely either SWITCH OFF ( no conduction ) or SWITCH ON ( full saturation conduction ) . One stage would hold the other stage in its recently switched state.

 

Thus the first binary memory was possible . Namely a 1 or a 0 . Then came the ability to add and subtract electronically , binary . . 10010110.. (8 bits is 1 byte ) . The rest is history

A million of them a Megabyte. A billion of them is a Gigabyte. My I pad memory is 50 gigabytes. That's a ' flipping lot ' ! Or a lot of flip flopping !
