I prototyped a circuit with one NPN and one PNP transistor, with an
LED/resistor between their collectors.  With even a 1M resistor
between the bases (and no other connection on the base side), enough
current flowed to light the LED.

I tried a couple of other variations; none seemed to do what I wanted.
Any kind of connection between the bases caused each transistor to
bias the other.
