Pummer on a Breadboard

Breadboarded up the circuit for Solarbotics' pummer kit. I'm building it without the PCB so I wanted to do a little proof of concept and planning for my free-forming. Surprisingly, it worked the first time I plugged in the batteries!

A pummer is like a nocturnal electronic plant. It absorbs light during the day through a solar cell and then at night, when darkness falls, it flashes an LED. It flashes the LED with a gradual decay, kind of like a charging Powerbook.

Is it possible to build one 74hc240 instead of 74ac?

I'm attempting to build the WSG and I guess I'm kind of confused by breadboarding. For the LED here, should it be shorted by the connection which goes between the two leads on the breadboard?

cool!!! but why it still lighting for a while?

but then it would just run out of charge. This thing recharges off light during the day. That's the whole point.
